BJT03209E SET KEEPDEST requires a value
The SET KEEPDEST command was issued without a destination value. This startup command specifies a mask that is used to generate keep destinations for temporarily holding SYSOUT data sets. These keep destinations are only for SYSOUT data sets that are captured based on a selector or subselector rule that specifies both a Combine Sysout value of YES and a normal Disposition value of DELETE. If you specify no destination value for the SET KEEPDEST command, Output Manager will use the default mask of TOMGR.
Specify a five-character mask with the SET KEEPDEST command, or accept the default mask of TOMGR. Ensure that any mask you use will not generate keep destinations that conflict with the existing keep destinations that are in use at your site.
