RE: pausing a subfile

I had the same thought. I used the SLN technique awhile back to relay to
the user the last four [4] items entered on an order. But I did not read
(may have missed it) where there was a specific (max.) number of lines. So
if there is, after headers and footers, room for twenty [20] lines, would
happens on the twenty-first [21]? In my example, I just rolled up the lines
as they had served their purpose.

And I have been trying to figure out Why. I concede that Booth is a better
programmer than I, but it seems to be defeating the purpose of the subfile
concept. As a corollary to that, how does the user know When the subfile is
complete? The usual goal is to get the info to the user as quickly as
possible, not to have them sitting and waiting; i.e., sub-second response
time. I just have no imagination.

Booth,

Is this for an "output only" application? Maybe the old SLN technique
would work better, instead of a subfile.

Then you need to either change or override the display file with the
WAITRCD setting the required delay. Value is in seconds so you could
set this to 1 if you really wanted to.

In the program use the WRITE and READ instead of the EXFMT.

Code the File information DS for the Display file and include the
*STATUS option; Eg (Sorry old program and not free format)

F INFDS(INFDSA)

Workstation file information DS

D INFDSA DS
D DSPFIA *FILE
D STSFIA *STATUS

When you issue the READ include an error indicator which will be set
on if the WAITRCD time expires, test the STSFIA for a value of 01331
to confirm this is a time-out and then modify the subfile and re-display

it.

If you want that degree of sophistication in a green screen interface
then you need to use something like the DSM APIs so that you control
the display rather than Workstation Data Management controlling when
the data is sent to the device.

As has been noted a regular subfile is only updated when the control
record is displayed.

Frankly Booth you are trying to do something that 5250 terminals were
never really designed to do.

This seemed simple enough but it has me stumped.

I am adding lines to a subfile. I want the user to see each line as

is added, using sleep() instead of exfmt. (Thank you for the links on
that earlier. Works great.)

Writing the new subfile record and then writing the control record
and

sleep(1) seemed like the right choice. It apparently isn't. Any ideas?
