Expressions (CTM)

Expressions are used to specify selection criteria. The format of an expression is

where

• key is a parameter (field) in the record. Each key listed in each INCLUDE / EXCLUDE statement must be unique.
• operator is a relational symbol used to compare the key to the value. Supported symbols include:

  = – equal
¬ or ! – not equal
< – less than
> – greater than

• value – Number or character string (that can include mask characters) against which to compare the key.

Note: When specifying Hexadecimal numbers, these values must be prefixed with an X (for example, DVLRBA=X01234567 instead of DVLRBA=01234567), except in relation to VER and REP fields. For valid values that can be specified in INCLUDE / EXCLUDE statements in Control-M/Tape, see the discussion in the appendix to the INCONTROL for z/OS Administrator Guide that discusses logical field names for the Control-M/Tape Repository.

Only the =, ¬ and ! operators can be specified when the key and value are of type character (meaning, non-numeric).

Mask characters can be specified:

• for expressions whose operator is either =, ¬ or !

  -and-

• as part of a character string

For additional information about masking, see the online facilities chapter in the appropriate user guide.
