The criterion for "more efficient" should consider the cost of human resources, before computer resources.
o "Industry standard"? Not any more. (But I can remember when ISPF (at the time SPF) panels were distributed as VB; IBM later switched to FB (circa 1980?). o When Rexx for TSO/E was first announced, I saw an IBM Intro publication which recommended VB without line numbers and liberal use of mixed case for human legibility (I sense MFC's hand here). I can no longer find that pub, and IBM imediately failed to walk their talk. o ISPF is the _only_ editor/viewer I know that won't soft-wrap long lines to fit the screen without scrolling back and forth (although some rely on auto-scrolling to follow the cursor). Particularly painful when I want to insert a few characters in a line that has more than 80 (or whatever) characters to the right of the insertion point. I need to Change and overtype. Or when I delete a character, a blank gets inserted at the point of the right screen boundary and I must scroll right and delete it. There should be a Requirement for ISPF (optionally, in profile) to soft-wrap long lines to screen width. (Or is there such a Requirement already?) I just go use another editor rather than fight it.
