Rules for Repeating Operands

There are some commands whose formats can repeat themselves or are actually compound commands, such as DCP ml0.10 nl0.10. This is called a compound command. When CP executes a compound command, the repeating operands are actually treated as separate commands.

DCP ml0.10
DCP nl0.10

To make rule writing more consistent and easy to follow, CA ACF2 for z/ VM also treats this as two separate commands and passes the command through the rule set twice, as if they were separate. After separating the commands, only those commands that are authorized by a rule are allowed. For example, a user might be authorized to issue DCP m10.10, but not authorized to issue DCP n10.10.

You can determine if a command repeats by examining its command model. If the REPEATS verb is specified in the FORMAT or GROUP clause, it is a repeating command. For more information, see the “Using the Model Setting” chapter.
