Executable Block Statements - KEEP

The system will only assign values which are needed. Sometimes, even though a value does not seem to be needed immediately (it is not sent to output) it is desirable to save it for later use. This can be indicated by the KEEP statement followed by a list of the variables to be kept.

ALL_VAR may be used in the KEEP statement to KEEP all variables, system and user-defined.

Example:

FEED: KEEP MCH_FEED;
