Symbolic Replacements

Description Symbolic replacements replaces a set of characters found in your JCL.

These replacements are useful for setting JCL subparameters or

comments at execution time.

BIM-EPIC inserts the replacement value into the statement and shifts to

the right any data following the replacement symbol. For example:

* JMCL &1='INVENTRY.INPUT'

// TLBL SORTOUT,'&1',,,,,,2

would result in:

// TLBL SORTOUT,'INVENTRY.INPUT',,,,,,2

WARNING:

You must avoid truncation of a statement exceeding 71

characters. A JCL statement cannot exceed 71 characters.

Symbolic replacements are not valid on POWER JECL statements or in

SYSIPT data. Any other statement, including JMCL statements, can use

symbolic replacements.

You should assign values to symbolic replacements on OPTION

statements.

&n The symbolic replacement parameter has the format &n, where n is a

number between 0 and 9. Use the symbolic replacement parameter to

replace characters with the value you assign to the symbol.

You can have up to 10 symbolic replacements in effect at the same time.

Each parameter remains in effect until it is re-assigned in a JMCL or

OPTION statement or until it is nullified with RESET, or end-of-job

occurs. The following is an example of a command statement containing

a symbolic replacement parameter.

&n='constant'

Definitions The following provides definitions for the parameters you can use when
