Reader Feedback and Insights: QTEMP and the Library List

There seems a chance of contradictory behavior with that. If references to QTEMP are always hard coded, then perhaps QTEMP should not be in the library list.

And if QTEMP must be in the list in order to catch possible *LIBL references,

 393K - No compression
 242K - DTACPR(*YES)
 116K - DTACPR(*NO), PKZIP'ed
 117K - DTACPR(*YES), PKZIP'ed

Of course, this assumes that the recipient can unzip the file, but nearly everyone has PKZIP or WinZip or some variant.

It’s interesting to note that you usually get the best compression by saving with DTACPR(*NO) and letting PKZIP do its thing on the
