Re: Display subfile page number

Booth,

Thanks for the response.

I would add one more troublesome issue with scroll bars - they only work on sessions with the enhanced data stream (I think that's what it's called). Many of our users have thin clients that don't support the eds. While they can still run the program, they don't get the benefit of the scroll bar.

BTW, thanks for mentioning the SFLSIZ issue. I always wondered why the scroll bar seemed a little out of whack. That makes sense.

Thanks.

Two issues with scroll bars sometimes are troublesome.

One of course is the three columns needed on the right side to display the subfile. The good news is that showing the scrollbar is a one-word change in the DSPF (unless the SFLSIZE keyword is some arbitrarily too-high value).

The other issue programmers sometimes get tripped up on is that the SFLSIZE needs to be correct. (Just making the subfile size some arbitrarily too-high number compiles and works, but if you use the actual subfile size then the program can do the math correctly and make the slider on the scrollbar the right proportion compared to the subfile size, and also place the slider correctly on the scrollbar so the user gets two visual signals about the relative size of the subfile, and where s/he is in the subfile.
