This document covers the following topics:
When you define chapter titles, a table of contents is automatically created. When you define index entries, an index is automatically created.
The different parts of a formatted document are output in the following sequence:
document text (including all embedded documents at the specified positions)
index
table of contents
You can merge several source documents into a single output document (i.e. the formatted version of all source documents). To do so, you use the .EM instruction.
The documents to be embedded may either contain short texts (e.g. standard phrases which you include in a letter) or long texts (e.g. a chapter of a book).
When you write a book, you can create a document which contains all .EM instructions and which thus controls the output of all chapters of the book.
.EM document-name
To embed a document in the current document (i.e. the document containing the .EM instruction), you must specify the .EM instruction with the name of the document that you want to embed. For example, to embed the document named "preface", you must specify:
.EM preface
If the document name consists of several words which are separated by blanks, the document name must be specified in single quotation marks. For example:
.EM 'new strategy'
No special instruction is needed at the end of an embedded document. Con-form automatically returns to the document which contained the .EM instruction and continues processing the information following the .EM instruction. However, if required, you can also use the .EF instruction (see below).
The document specified by the .EM instruction may also contain .EM instructions. This process may be continued up to a maximum nesting depth of 5.
.EF
When you want to embed only the beginning of a document, you can include the .EF instruction in the document that you want to embed.
Upon encountering this instruction, Con-form returns control to the document which contains the .EM instruction and continues processing the information following the .EM instruction.
All information in the embedded document which follows the .EF instruction is not considered.
.EP
You can include the. EP instruction in any document (it need not necessarily be an embedded document) to stop formatting.
In the case of an embedded document, Con-form does not return control to the document which contains the .EM instruction.
It is not possible to conditionally suppress the processing of the .EP instruction by using it in an .IF construction. Formatting is always stopped.
.OP EMN=ON .OP EMN=OFF
You can only use the instruction .OP EMN=ON when filling is switched on (.FI ON).
When you embed a document in another document, the text after the embedded document always starts in a new line - even if filling is switched on.
To disallow the line break, you must specify the following:
.OP EMN=ON
As a result, the text of the current document continues in the same line as the text of the embedded document.
Initially, this option is switched off. This corresponds to the following:
.OP EMN=OFF
This example illustrates how to embed a document. When the embedded document contains no specific instructions, it is formatted according to the instructions given in the document which contains the .EM instruction. However, instructions in the embedded document (e.g. values for margins, filling and justification) also apply to the document which contains the .EM instruction. Therefore, you must take care to reset these values at the end of the embedded document.
.LM 10;.RM 60 .FI ON;.JU OFF This is the document to be embedded. When it is embedded in another document, it is formatted according to the instructions defined here. .LM 0;.RM 70 .FI ON;.JU ON
.LM 0;.RM 70 .FI ON;.JU ON To include the text from another document into the current document, you must specify the .EM instruction with the name of the document to be embedded. .IL 1 .EM doc2 .IL 1 When you do not reset the values in the embedded document, they are also applied to the main document.
To include the text from another document into the current document, you must specify the .EM instruction with the name of the document to be embedded. This is the document to be embedded. When it is embedded in another document, it is formatted according to the instructions defined here. When you do not reset the values in the embedded document, they are also applied to the main document.
If a part of your document is to be formatted differently than the main part of it, you can save the current settings of the document with the .SA instruction. For the next section of text, you can then modify the settings as required. Later you specify the .RS instruction to restore the original settings which have been saved with the last .SA instruction and continue processing.
Note:
This feature is helpful when you want to embed a document.
.SA
To save the current settings of the document, you must specify the .SA instruction.
You can then modify the settings as required. For example, you can define different left and right margins for the text after the .SA instruction.
The following actions automatically issue the .SA instruction:
.NL KEEP
.NL FLOAT
The processing of footnotes (.FN)
The processing of header lines (.HL)
To restore the original settings which have been saved with the last .SA instruction, you must use the .RS instruction (see below).
.RS
To restore the settings which have been saved with the last .SA instruction, you must specify the .RS instruction.
As a result, formatting continues with the settings which were in effect before the last .SA instruction was executed.
The following actions automatically issue the .RS instruction:
.NL OFF
The completion of the processing of footnotes (.FN)
The completion of the processing of header lines (.HL)
This example illustrates the instructions .SA and .RS.
.LM 0;.RM 70 .FI ON;.JU ON You can use the .SA instruction to save the current settings (for example, the settings for the margins, filling and justification). .SA .** Define different settings for the following lines. .LM 10;.RM 50 .FI ON;.JU OFF .IL 1 Different margins have been defined for this part of the document and justification has been switched off. .IL 1 .** Restore the previous settings. .RS When you use the .RS instruction, the previously stored settings are restored and formatting continues with the settings which were in effect before the .SA instruction was executed.
You can use the .SA instruction to save the current settings (for example, the settings for the margins, filling and justification). Different margins have been defined for this part of the document and justification has been switched off. When you use the .RS instruction, the previously stored settings are restored and formatting continues with the settings which were in effect before the .SA instruction was executed.
You define chapter titles with the .CH instruction. The titles are output in the current position of the text as well as in the table of contents. The table of contents is automatically output at the end of the document, starting on a new page. When you also specify index entries, the table of contents is output after the index.
You can use the .PT instruction to control the layout of the table of contents.
.CH number .CH +number .CH -number .CH
To define chapter titles and make entries in the table of contents, you must use the .CH instruction. The text which follows the .CH instruction - before the next line break - is the chapter title. For example:
.CH 1 Chapter One
The title is output at the current position in the text and in the table of contents. The parameter after the .CH instruction defines the level (see Defining Different Levels for Titles).
Con-form automatically checks whether at least 7 free lines are available on the current page (i.e. Con-form implicitly performs the instruction .NL 7). If seven lines are not available, Con-form starts a new page and outputs the title on the new page. Thus, a chapter or section will not start near the bottom of a page.
When filling is switched on (.FI ON), a line break must occur after the title. Otherwise, all text between the .CH instruction and the next line break is interpreted as the title and included in the table of contents. For example:
.FI ON;.JU ON .CH 1 This is the chapter title. When filling has been switched on, you must ensure that a line break occurs after the chapter title. .IL 1 All text between the .CH instruction and the next line break is included in the table of contents.
The above instructions cause the following formatted output:
1. This is the chapter title. When filling has been switched on, you must ensure that a line break occurs after the chapter title. All text between the .CH instruction and the next line break is included in the table of contents.
The table of contents is automatically output at the end of the formatted document:
1. This is the chapter title. When filling has been switched on, you must ensure that a line break occurs after the chapter title...... 1
To define a line break, you can either leave blank lines in the source text or specify the end-of-line character which is usually the dollar sign ($). See Starting Text on a New Line for further information concerning line breaks.
To define different levels, you must specify the level as a parameter with the .CH instruction. For example:
Instruction | Level | Numbering Style |
---|---|---|
.CH 1 | Chapter Title | 1 |
.CH 2 | Section Title | 1.1 |
.CH 3 | Subsection Title | 1.1.1 |
.CH 4 | Subsubsection Title | 1.1.1.1 |
Note:
The parameter after the .CH instruction is not the number of the
chapter, but the level of the title. The chapter number is automatically
increased by one when the next .CH 1 instruction (i.e. a title on the first
level) is encountered.
You can define up to ten different levels for titles and up to 99 entries for each level. Each time a .CH instruction is processed, a chapter number is automatically built. The chapter number is stored in the variable $CH (see Modifiable System Variables).
When you specify the level as a parameter with the .CH instruction, the titles are initially numbered. However, you can switch chapter numbering off (see the instruction .OP CHA).
Initially, the entries in the table of contents are indented. However, you can switch indentation off (see the instruction .OP CHI).
Note:
When you do not want to use different levels for your titles, you
need not specify a number with the .CH instruction. In this case, the titles
are neither numbered nor indented in the table of contents.
The following example shows how to define titles on different levels:
.CH 1 Chapter Title This is the text below the chapter title. .IL 1 .CH 2 Section Title This is text below the second level section title. In the table of contents, all titles below level 1 are automatically indented. .IL 1 .CH 3 Subsection Title This is text below the third level subsection title. .IL 1 .CH 1 Chapter Title This is chapter two.
The above instructions cause the following formatted output:
1. Chapter Title This is the text below the chapter title. 1.1 Section Title This is text below the second level section title. In the table of contents, all titles below level 1 are automatically indented. 1.1.1 Subsection Title This is text below the third level subsection title. The table of contents is output at the end of the formatted document. 2. Chapter Title This is chapter two.
The table of contents is output as follows:
1. Chapter Title..................................................... 1 1.1 Section Title.................................................. 1 1.1.1 Subsection Title........................................... 1 2. Chapter Title..................................................... 1
You can also use a plus or minus sign to define the number of levels higher or lower than the current level. When you specify the instruction .CH +0, the next title is output at the same level as the current title.
The following example shows how to define titles on different levels:
.CH 1 Chapter One To define the next chapter title at the same level, you specify .CH +0. .IL 1 .CH +0 Chapter Two To define a section title within the second chapter, you specify the number of levels higher or lower. .IL 1 .CH +1 This is the section title .CH +1 A subsection .CH -1 Another section title .CH +1 First subsection .CH +0 Second subsection .CH +0 Third subsection .IL 1 .CH 1 Chapter Three
The above instructions cause the following formatted output:
1. Chapter One To define the next chapter title at the same level, you specify .CH +0. 2. Chapter Two To define a section title within the second chapter, you specify the number of levels higher or lower. 2.1 This is the section title 2.1.1 A subsection 2.2 Another section title 2.2.1 First subsection 2.2.2 Second subsection 2.2.3 Third subsection 3. Chapter Three
The table of contents is output as follows:
1. Chapter One....................................................... 1 2. Chapter Two....................................................... 1 2.1 This is the section title...................................... 1 2.1.1 A subsection............................................... 1 2.2 Another section title.......................................... 1 2.2.1 First subsection........................................... 1 2.2.2 Second subsection.......................................... 1 2.2.3 Third subsection........................................... 1 3. Chapter Three..................................................... 1
At the current position in the text, the title is not automatically formatted in a specific way. For example, to emphasize the title or print blank lines before and after it, you must include the appropriate instructions in the source text:
.CH 1;.US;.** Underscore the next line Chapter One .IL 1 .CH 1;.BP;.** Print the next line in boldface Chapter Two .** Print the next chapter title in italics. .** The escape sequence /I1 was entered in a separate line. .** When the escape sequence is entered directly in front of the words .** "Chapter Three", the number is not printed in italics. .OP ESC=/ /I1 .CH 1 Chapter Three/I0
The above instructions cause the following formatted output:
1. Chapter One 2. Chapter Two 3. Chapter Three
The table of contents is not influenced by the above instructions:
1. Chapter One....................................................... 1 2. Chapter Two....................................................... 1 3. Chapter Three..................................................... 1
To control the layout of the table of contents, you must use the .PT instruction.
.OP CHA=NUM .OP CHA=UNN
When you specify the level as a parameter with the .CH instruction, the titles are initially numbered. This corresponds to the following instruction:
.OP CHA=NUM
To switch chapter numbering off, you must specify:
.OP CHA=UNN
For example:
.OP CHA=UNN .CH 1 Chapter 1 This is the first chapter. .CH 2;.IL 1 Section 1.1 This is the first section. .CH 2;.IL 1 Section 1.2 This is the second section. .CH 1;.IL 1 Chapter 2 This is the second chapter.
The above instructions cause the following formatted output:
Chapter 1 This is the first chapter. Section 1.1 This is the first section. Section 1.2 This is the second section. Chapter 2 This is the second chapter.
The table of contents is output as follows:
Chapter 1............................................................ 1 Section 1.1........................................................ 1 Section 1.2........................................................ 1 Chapter 2............................................................ 1
Initially, the entries in the table of contents are indented. However, you can switch indentation off (see the instruction .OP CHI).
.OP CHI=ON .OP CHI=OFF
When you specify the level as a parameter with the .CH instruction, the titles in the table of contents are initially indented - according to the level you specified. This corresponds to the following instruction:
.OP CHI=ON
To switch indentation off, you must specify:
.OP CHI=OFF
For example:
.OP CHI=OFF .CH 1 Chapter One This is the first chapter. .CH 2;.IL 1 First Section This is the first section. .CH 2;.IL 1 Second Section This is the second section. .CH 1;.IL 1 Chapter Two This is the second chapter.
The above instructions cause the following formatted output:
1. Chapter One This is the first chapter. 1.1 First Section This is the first section. 1.2 Second Section This is the second section. 2. Chapter Two This is the second chapter.
The table of contents is output as follows:
1. Chapter One....................................................... 1 1.1 First Section.................................................... 1 1.2 Second Section................................................... 1 2. Chapter Two....................................................... 1
.OP CHL=number
When you specify the level as a parameter with the .CH instruction, you can define a maximum of 10 different levels. This corresponds to the initial setting:
.OP CHL=10
You can specify the maximum level of titles that is included in the table of contents. All titles with levels greater than the number specified with the .OP CHL instruction are not included in the table of contents. For example:
.OP CHL=2 .CH 1 Chapter Title The chapter title at level 1 is included in the table of contents. .CH 2;.IL 1 Section Title The section title at level 2 is included in the table of contents. .CH 3;.IL 1 Subsection Title The subsection title at level 3 is not included in the table of contents.
The above instructions cause the following formatted output:
1. Chapter Title The chapter title at level 1 is included in the table of contents. 1.1 Section Title The section title at level 2 is included in the table of contents. 1.1.1 Subsection Title The subsection title at level 3 is not included in the table of contents.
The table of contents is output as follows:
1. Chapter Title..................................................... 1 1.1 Section Title.................................................. 1
When you do not want to include any titles in the table of contents, you must specify the following:
.OP CHI=0
When you specify the above instruction at the beginning of a document, a table of contents is not created. When you specify the above instruction after you have already included several titles in the table of contents, the titles after this instruction are not included in the table of contents.
.SC chapter-number
This instruction is only valid when .OP CHA=NUM is in effect, i.e. when chapter numbering is switched on.
You can define another chapter number for the current chapter or section. The next .CH n instruction then determines the chapter or section level. For example:
.CH 1 Chapter One .SC 4;.** Set the current chapter number to 4. .CH 1;.** Start a new chapter. The chapter number is increased by 1. Chapter Five
The above instructions cause the following formatted output:
1. Chapter One 5. Chapter Five
The table of contents is output as follows:
1. Chapter One....................................................... 1 5. Chapter Five...................................................... 1
As long as you do not specify a new level 1 chapter title (using the instruction .CH 1), all sections and subsections receive the chapter number which has been defined for the current chapter. When the instruction .CH 1 occurs after the .SC instruction, the chapter number is increased by one. For example:
.CH 1 Chapter Title .SC 4;.** Set the current chapter number to 4. .CH 2;.** Output a section title at level 2. Section Title .SC 7;.** Set the current chapter number to 7. .CH 2;.** Output another section title at level 2. Section Title .CH 3;.** Output a subsection title at level 3. First Subsection Title .SC 7.5;.** Set the current section number to 7.5 .CH 3;.** Output another subsection title at level 3. Second Subsection Title .SC 15;.** Set the current chapter number to 15. .CH 1;.** Start a new chapter with number 16. Chapter Title
The above instructions cause the following formatted output:
1. Chapter Title 4.1 Section Title 7.1 Section Title 7.1.1 First Subsection Title 7.5.1 Second Subsection Title 16. Chapter Title
In the table of contents, the titles are indented according to their levels:
1. Chapter Title..................................................... 1 4.1 Section Title.................................................. 1 7.1 Section Title.................................................. 1 7.1.1 First Subsection Title..................................... 1 7.5.1 Second Subsection Title.................................... 1 16. Chapter Title.................................................... 1
.PT instruction .PT text
You use the .PT instruction to control the layout of the table of contents. You can define text as well as instructions (or macros with parameters as necessary) with the .PT instruction. However, you must not mix text and instruction within a single .PT instruction.
For example, to print a centered and underscored title above the table of contents, you specify the following instructions:
.PT .CE 1;.US .PT Table of Contents
You can use the .HL instruction (to define a header which appears at the top of each page) as a parameter of the .PT instruction. Like the .PT instruction, the .HL instruction is also specified with either an instruction or text. For example:
.PT .HL .CE 1 .PT .HL Table of Contents
The .PT instruction must be entered at the beginning of the document. When you enter it, for example, at the end of the document, it may happen that the formatted output does not appear as desired.
The table of contents is always output at the end of the document. However, when you have printed the document, you can re-arrange the printed pages and move the table of contents to the beginning of the document. In this case, it is useful when a different page number style (for example, Roman page numbers) has been defined for the table of contents.
When you specify a top and/or bottom title for the document and do not define different top or bottom titles for the table of contents, the table of contents also contains the top and bottom titles of the main document. When page numbering has been defined, consecutive numbering continues from the last page of the actual document.
Tip:
When you work in Con-nect, you can file a formatted version of the
document and then modify the formatted version of the table of contents in the
Con-nect editor.
The following example illustrates how to output the page number in the bottom title of the table of contents and how to define upper-case Roman page numbers with number 1 as the first page.
.FI ON;.JU ON .PT .NP 1 .PT .PM R .PT .BT //ToC # .PT .US;.** Underscore the following line. .PT Table of Contents .PT .IL 1 .CH 1;.** Chapter numbering is switched on by default. The Table of Contents .IL 1 .CH 2 The .PT Instruction .IL 1 You use the .PT instruction to influence the layout of the table of contents. You can specify text or instructions with the .PT instruction. However, you must not mix text and instructions within a single .PT instruction. .IL 2 .CH 2 The .OP PTC Instruction .IL 1 By default, the .PT instruction is switched on. You can switch it off so that the text or instruction after a .PT instruction is not applied to the table of contents.
The above instructions cause the following formatted output:
1. The Table of Contents 1.1 The .PT Instruction You use the .PT instruction to influence the layout of the table of contents. You can specify text or instructions with the .PT instruction. However, you must not mix text and instructions within a single .PT instruction. 1.2 The .OP PTC Instruction By default, the .PT instruction is switched on. You can switch it off so that the text or instruction after a .PT instruction is not applied to the table of contents.
The table of contents is output as follows:
Table of Contents 1. The Table of Contents............................................. 1 1.1 The .PT Instruction............................................ 1 1.2 The .OP PTC Instruction........................................ 1
The page number is printed in the bottom title of the table of contents:
ToC I
.OP PTC=ON .OP PTC=OFF
Initially, the .PT instruction is in effect, i.e. the text or instruction after the.PT instruction is applied to the table of contents. This corresponds to the following instruction:
.OP PTC=ON
To switch this feature off, so that the text or instruction after the .PT instruction is not applied to the table of contents, you specify:
.OP PTC=OFF
.IX text
Index entries are made using the .IX instruction. For example:
.IX Index entries;; how to specify
The text to be included in the index can be up to 60 characters long and may contain any printable characters. If you want to include the instruction separator character (initially, this is the semicolon) in the index, you must repeat it (i.e. you must specify ";;").
The text defined with the last .IX instruction is stored in the variable $IX (see Modifiable System Variables).
Unlike the .CH instruction, the .IX instruction does not output the index entry at the current position in the text. It stores the index entry together with the number of the page on which the entry has been defined.
All index entries are automatically sorted alphabetically and output at the end of the document, starting on a new page. When your document also contains a table of contents, the index summary is output between the document text and the table of contents.
Lower-case letters precede the corresponding upper-case letters in the index summary. The sorting sequence is "aAbBcC ... zZ".
Note:
A specific sorting sequence can be defined while installing
Con-form.
When you used the .CH instruction in your source text, the index summary automatically receives the heading "Index". In addition, when chapter numbering was active (.OP CHA=NUM), the heading "Index" is preceded by the next chapter number. When the .CH instruction was not used in your source text, the heading "Index" does not appear.
"Index n" (where n is the page number) is automatically output at the bottom of all odd-numbered pages. Therefore, you should not use the .BT instruction to define page numbers in the bottom title. Consecutive numbering continues from the last page of the actual document - even if you did not define page numbers for your document. A page number is not output on an even-numbered page.
This example illustrates how to define index entries. Filling has been switched on. Therefore, the index entries do not cause line breaks in the formatted document. The .CH instruction has been used in the source text. Therefore, the index receives a chapter number and a table of contents is created. In this example, the index is output on an even-numbered page. Therefore, the page does not contain a page number.
Note:
When you work in Con-nect and file a formatted version of this
example document, the document format is Cnf (instead of Txt). This is because
the index contains an entry starting with a period (.IX).
