CAPS

To convert all values into caps, the CAPS-statement can be used.

CAPS ON;

CAPS OFF;

CHANGE

The CHANGE-statement is used to change the values of a focused object.

/* change the program of STEP1 to "TESTPGM" */
CHANGE
FILTER
    STMT = "EXEC",
    VALUE = "STEP1",
    PARM = "PGM"
EXEC
    NEWVALUE = "TESTPGM";

Since the PARM PGM is the last focused object, the NEWVALUE gets assigned to the value of PGM.

As mentioned in the rules introduction, the CHANGE-statement is deprecated and shouldn't be used in new rule sets.
