Even on a mod-2 when I run through the X/HIDE/F sequence on file SDSF2
the scrolling is odd. For example, about the third screen I scroll down
ok, but when I scroll back up I'm 1 line off from where I started.
I can reproduce this if the scroll amount is PAGE or CSR but if I put
say, 20 in the scroll field the problem goes away.
That's on z/OS 2.2

Hi all,
I'm visually comparing two datasets by excluding and hiding lines:
X ALL
HIDE X
F '*' 2 ALL
on both datasets, and the resulting screens are the same.
PF8 on both, resulting screens are the same
PF8 on both, resulting screens are the same
PF8 on both, resulting screens are not the same, one screen has been
scrolled one line less, so add an extra
1 PF8
on that one to re-synchronize, and
PF8 on both, resulting screens are the same
PF8 on both, resulting screens are not the same, one screen (same as above)
has been scrolled one line less
OK, enough, and lets do a
DEL X ALL
to remove all excluded (and hidden lines), followed by
LOCATE .ZF
on both.
And guess what, a PF8 on both screens will keep them in sync, not a
surprise, as I know with absolute certainty that both datasets contain
exactly the same number of lines with an asterisk in column two.
Further info?
Terminal emulator: Tom Brennan's most excellent Vista tn3270 V1.27 Nov 12
2014, with a screen size of 62x160
and from the 7.3 variables list:
ZENVIR S N ISPF 6.1MVS TSO
ZISPFOS S N ISPF FOR z/OS 01.11.00
I have abso-flipping-lutely no explanation for this behaviour, any
suggestion as to why this happens would be most welcome!
If you want the two files, they come in either a 22kb WinRar (ftp.rar)
archive, or a 49kb ZIP (ftp.zip) archive, and once UnRAR'ed or unZIP'ed,
are plain text, and on the system here both are in VB datasets with a
LRECL=515. They're on my Google drive @
