I remember ICCF<?> did in fact do real time updates when you hit enter (at least under the setup we had all those years ago .....)

Whether the lines on the screen have trailing blanks or nulls is an option you or your installation set. I suspect if the file actually has trailing blanks, those will be on the screen, but I have no reason or desire to test it. It's useful to think of "being in" the file while editing, but this is just an abstraction. ISPF allows you to lengthen or shorten records, add, delete, or change them, etc... You know this doesn't modify the file at all until you save, and that is when ISPF builds actual records. Pretending there are a bunch of blanks there on the screen is merely a cosmetic thing they decided to do. Nulls would have made more sense to me, but again, as this is merely cosmetic, I really don't care. Anyway, how the screen works and how the file is stored are two different things; it is due to ISPF's great design that it appears seamless. A counter-example is FM, which refuses to allow you to change the length of a record in a KSDS (as far I could tell, quite a while ago). sas On Thu, Aug 8, 2019 at 10:35 AM Steve Thompson <[email protected]> wrote: > If it doesn’t pad out the lines, how would you write into those > records, after the last character (defined by the RDW)? > > This would be why, in my best guess, it is done like that with edit. > > Sent from my iPhone — small keyboarf, fat fungrs, stupd spell manglr. > Expct mistaks > > > > On Aug 8, 2019, at 8:46 AM, Steve Smith <[email protected]> wrote: > > > > Option 1 defaults to "View" mode, which is like Edit.
