This document describes the advantages and the use of copycode.
The following topics are covered:
Copycode is 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 copycode 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 object module.
Consequently, when you modify the source code of copycode, you also have
to catalog all objects which use
that copycode using the CATALOG 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).
