VAL={aa }
-----------------
{(aa,bb,...)}Two alphanumeric characters (such as, A1 or 30) are appended to VATLST to specify the VATLSTxx member(s) of parmlib. If the parameter is not specified either in IEASYSxx or by the operator, the default member VATLST00 is used, if it exists. If the VAL parameter specifies multiple members, the members are processed in the order specified. If a particular volume serial number appears on more than one entry, the volume attributes specified in the last entry for that volume serial will be accepted. If the VAL parameter has an invalid format, or if it specifies a member that does not exist in parmlib, the operator is prompted to respecify the member or to reply ‘U’ to cause the member to be ignored.
