The FIND command differs from the LOCATE
command in the following ways:
The FIND command is more effective for text searches while
the LOCATE command is used primarily to find line numbers
or line labels.
The LOCATE command finds only text in upper case beginning
in column one of the editor. In addition, in order to find a string, the data in the
editor must be in alphabetical order.
When a line is located with the LOCATE command, the cursor
is placed in the prefix area and the line is placed at the top of the editor; with the
FIND command, the cursor is placed on the string searched
and the line is not necessarily placed at the top of the editor.
To repeat the execution of a FIND command, use the command
RFIND.
F C'NAME' .X .Y ALL PREFIX X
This command searches for any occurrence of NAME exactly as entered here as
a prefix of a word in any excluded line within the block delineated by .X and
.Y.
F C'HILITE' X PREV
This command searches for the previous occurrence of HILITE exactly as
entered here in any excluded line.
F P'RCV#' .X .Z 20 30
This command searches for any 4-character string that begins with RCV and
whose fourth character is numeric. It searches within the block of lines delineated by
.X and .Z and between columns 20 to 30.
F X'6C' SUFFIX NX
This command searches for the character with hexadecimal representation 6C.
Only those occurrences of the character that are at the end of word are found. The search
is valid for non-excluded lines only.
F '''w'
This command searches for the following character string: 'w.
F 'r''w'
This command searches for the following character string: r'w.
F ''''
This command searches for an apostrophe.

When you then mark a line with a TO line command (or a block
of lines with two TOO line commands), the data between columns
10 and 60 in the marked line(s) is left-aligned to column 10.
LABEL .label |
This command is used to mark the current line (that is, the line which is currently at
top of the editing area) with the specified
.label.
The label may be a string of 1 to 4 alphabetic
characters.
To label the current line with .X, you enter the command:
LABEL .X
You can also mark a block of lines with two labels. For example, to mark a block with
labels .X and .Y, you first mark the current line (assuming it
is the first line of the block to be marked) with .X as shown in the example
above; then you scroll until the last line of the block is the current line; then you
issue the command LABEL .Y to mark that line with
.Y.
To mark a line with a label, you can also use the line command

[tab-character]
[column...] |
|||||
This command is used to control tabulator settings.
You can enable or disable logical or physical tabulation by using the command
TABS ON or TABS OFF. Tabulation is
also enabled by any command that changes a tabulation setting.
For example, the following command enables logical tabulation with the ampersand sign (&) as logical tabulation character:
TABS &
You set tab positions by using the TABS command. For example,
the following command sets tabs in columns 10, 20 and 30:
TABS 10 20 30
You can enter data and automatically move it to a specific tab position by preceding it with a logical tabulation character. One tabulation character moves the data to the next tab position, two tabulation characters move the data to the second tab position, and so on.
To display the current TABS command settings, issue the main
command PROFILE.
To display the current tab positions, issue the line command
TABS.
The default setting is TABS OFF blank and can be changed by
editing your profile; see Setting the
Editor Profile.
Apart from tab positions, you can specify the following parameters with the
TABS command:
LEFT |
Places the data left-justified at the tab position. |
|---|---|
RIGHT |
Places the data right-justified at the tab position. |
DECIMAL |
Places the data so that the decimal point in the data is at the tab position. |
To tabulate data in a specific column, multiple tab characters are possible: issue the
TABS line command and type over each asterisk (*) marking the
tab positions with another special character. Any input preceded by any of these special
characters are tabulated in the corresponding column. You can type an L (for
LEFT), an R (for RIGHT) or a
D (for DECIMAL) after each tabulation character to
specify placement of data for the tab position.
Note
For further instructions and examples of using tabulation, see also Using the Physical or Logical
Tabulator.
TOP
|
This command is used to scroll to the beginning of the object being edited.
UC |
|
|
|

|
|
|
|
|
|
The UC command converts one or more lines to upper case. It
applies the same parameters as the LC command. If you enter the
UC command without parameters, it changes the current line to
upper case.
UNDO |
|
|
|
If the log file is active (see the LOG command), the
UNDO command backs out all changes made since the last time
you pressed ENTER. Repeated use of the UNDO command
backs out consecutive changes in reverse order. You can thus back out all changes one by
one until you restore the source to its original status at session begin.
You can specify the following parameters with the UNDO
command:
ALL |
All modifications made in the current editing session are backed out. |
|---|---|
n
|
The last n modifications are backed
out.
|
UNREN [n
m] |
Deactivates the renumbering of lines.
n |
Specifies the starting column of the line numbers (default: 73). |
|---|---|
m |
Specifies the end column of the line numbers (default: 80). |
To activate line renumbering, see the RENUMBER command.
UP [n]
|
This command scrolls upwards in the data.
The parameter n specifies the number of
lines to be scrolled upwards. If n is omitted, the
scroll amount is determined by the scroll mode.
WINDOW l1
l2 |
|
|
|
This command is used to define a data window to be copied or moved. The starting line and
column and the end line and column of the window are specified in the command parameters.
At least l1 and
l2 are required.
l1 l2
|
Defines a window starting at column 1 of line
l1 and ending in the last column of
line l2.
|
|---|---|
l1 l2
n
|
Defines a window starting at column n
of line l1 and ending at the last column
of line l2.
|
l1 l2 n
m
|
Defines a window starting at column n of line
l1 and ending at column
m of line
l2.
|
Note that all data in the source work area within the specified points becomes part of the window. For an example, see the section Copying a Window with Data.
XSWAP
|
The command is used to exchange displayed lines with excluded lines. Lines are excluded
by using the EXCLUDE command.
There are some options which are available with several main commands. These options are described in the following section.
The editor provides a command redisplay feature: if you precede a command with two ampersands (&&), it remains displayed in the command line and is executed every time you press ENTER until you delete the command or replace it.
With these options, you can restrict the effect of a command to a certain range of lines:
.X |
The command affects only the lines from the line labeled .X to
the last line.
|
|---|---|
.X .Y
|
The command affects only the lines from the line labeled .X to
the line labeled .Y.
|
X and Y can also be any label of 1 to 4 alphabetic characters
(see the LABEL command).
With these options, you can restrict the effect of a command to a certain range of columns. These column numbers refer to the actual data columns; the line numbers preceding the data are not counted. So, if you specify column 1 with a command, this may physically be the 8th column of your screen, but it is in fact the 1st column of the data you are editing.
n |
The command affects only lines in which the specified
string begins in column
n (that is, the first character of
the string must be in column
n).
|
|---|---|
n
m |
The command affects only lines in which the specified
string occurs anywhere between
columns n and
m.
|
With one of the following options, you can specify that only excluded or only included lines are to be affected by a command:
NX |
The command affects only non-excluded lines; that is, lines which are currently being displayed. |
|---|---|
X |
The command affects only excluded lines; that is, lines which are currently
not being displayed as specified by the EXCLUDE command. An excluded line
remains excluded from display if a main command function is performed on
it.
|
With these options, you can specify the direction in which a command is to operate:
NEXT |
The command affects the next line (starting from the cursor position) in
which the specified string
occurs.
|
|---|---|
PREV
|
The command affects the line that contains the previous occurrence of the
specified string.
|
FIRST
|
The command affects the first line in which the specified
string occurs.
|
LAST
|
The command affects the last line in which the specified
string occurs.
|
ALL
|
The command affects all lines in which the specified
string occurs.
|
With these options, you can specify whether only special occurrences of the specified
string are to be affected by a command:
CHARS |
The command affects any line in which the specified
string occurs.
|
|---|---|
WORD
|
The command affects only those lines in which the specified
string forms a word.
|
PREFIX
|
The command affects only those lines in which the specified
string is the beginning of a
word.
|
SUFFIX
|
The command affects only those lines in which the specified
string is the end of a word.
