Enhancements:

SUBSEL/SUBSET Command

• Based on the query3k SUBSET command.
• SUBSEL/SUBSET is a shortcut command to refine the current selection.
• May be abbreviated SUB.
• Performs an implicit FIND with INSEL=* and creates a new OUTSEL with the same set list as the previous FIND or SUBSEL.
• Supports all FIND statements, except PRIMARY, INSEL and OUTSEL which are automatically set.
• Use UNDO to step back to the previous selection.

Example:

FIND PRIMARY=MEMBER-FILE;OUTSEL=(@)
(LOAN-FILE.BALANCE > 100000)
Current OUTPUT select file is ./ASK97701
using serial read
entries read 396 591
entries qualified 107

SUB LOAN-FILE.ACTION <> "O"
Current INPUT select file is ./ASK97701
Current OUTPUT select file is ./ASK97702
using previous select file
entries read 107 107
entries qualified 93

UNDO Command

• Based on the query3k UNDO command.
• Switches the current select file back to the results of the previous SUBSEL/SUBSET or FIND command.

Example:

UNDO
Current select file is ./ASK97701
entries qualified 107

Fixes:

• Fix a bug with global OUTER keyword when the OUTSEL was an explicit set list, not "@".
