For an explanation of the symbols used in the syntax diagram, see Syntax Symbols.


Function

The INCLUDE statement is used to include source lines from an external object of type copycode into another object at compilation.

The INCLUDE statement is evaluated at compilation time. The source lines of the copycode will not be physically included in the source of the program that contains the INCLUDE statement, but they will be included during the program compilation and thus in the resulting object module.

Caution:
A source code line which contains an INCLUDE statement must not contain any other statement.

Syntax Element Description:

Syntax Element Description
copycode-name
Copycode Name:

As copycode-name you specify the name of the copycode whose source is to be included. The case of the specified name is not translated.

copycode-name may contain an ampersand (&); at compile time, this character will be replaced by the one-character code corresponding to the current value of the Natural system variable *LANGUAGE. This feature allows the use of multilingual copycode names.

The object you specify must be of the type copycode. The copycode must be contained either in the same library as the program which contains the INCLUDE statement or in the respective steplib (the default steplib is SYSTEM).

When the source of a copycode is modified, all programs using that copycode must be compiled again to reflect the changed source in their object codes.

The source code of the copycode must consist of syntactically complete statements.

operand1
Insert Values for Dynamic Insertion:

You can dynamically insert values in the copycode which is included. These values are specified with operand1.

In the copycode, the values are referenced with the following notation:

&n&

That is, you mark the position where a value is to be inserted with &n&. n is the sequential number of each value passed with the INCLUDE statement. For example, &3& would refer to the third value specified with the statement.

For every &n& notation in the copycode you must specify a value in the INCLUDE statement. For example, if the copycode contains &5&, operand1 must be specified at least five times.

You may write one copy code parameter (&n&) after another without blanks (that is, &1&&2&&3&). This method is used to concatenate multiple copy code parameters to a source.

A string may follow one or several copy code parameters without a blank (that is, &1&abc or &1&&2&abc). This method is used to concatenate a string to multiple copy code parameters.

Note:
Because &n& is a valid part of an identifier, this notation may not be used as a copy code parameter substitution in other positions described above (i.e. abc&1& or &1&abc&2&). In other words, a string may only come after copy code parameters, not before or between.

Values that are specified in the INCLUDE statement but not referenced in the copycode will be ignored.
