When you use an asterisk (*) as a character in an ID name, it functions as a wildcard; any character can fill that position. This is useful in defining PSBs to specific groups. For example, you can enter the following command:
GROUP(2) PSB (PAY* E***OY,*ALES)
The group now includes any PSB that begins with PAY, any PSB that begins with E and has O and Y in the fifth and sixth positions, and any PSB that has A, L, E, and S in the second through fifth positions.
Trailing asterisks (such as in PAY*) match all remaining characters. For example entering PAY**** is the same as entering PAY*. Asterisks in other positions match only one character.
Setting options and defining groups
You can set options and define groups for the collector either at startup time or during collection.
To set options at startup time, specify the OPTION keyword with the START command. If no OPTION= is specified, EPILOG uses the defaults. For example:
START EPILOG OPTION=member_name
The member name is the name of the dataset member in which the options are kept. The RKANPAR DD in the EM PROC defines the PDS which contains the specified member.
During collection, you can change the options with the VARY command. See “VARY command” on page 42.
