This document describes the advantages and the use of copycode.
The following topics are covered:
An object of type copycode contains a portion of source code which can be included in
another object via an INCLUDE
statement.
So, if you have a statement block which is to appear in identical form in several objects, you may use a copycode object instead of coding the statement block several times. This reduces the coding effort and also ensures that the blocks are really identical.
The copycode is included at compilation; that is, the source-code lines from the copycode
are not physically inserted into the object that contains the INCLUDE statement, but they will be
included in the compilation process and are thus part of the resulting cataloged
object.
Consequently, when you modify the source code of copycode, you also have to catalog all
objects which use that copycode using the CATALOG or CATALL system command.
Attention:
Copycode cannot be executed on its own. It cannot be stowed
with a STOW system command, but only
saved using the SAVE system
command.
An END statement must not be
placed within a copycode.
For further information, refer to the description of the INCLUDE statement (in the
Statements documentation).
