I am opening the file for update and did consider a file lock problem. I do get the same problem in our test system where I'm the only one accessing these files. As far as other processing, I chain out to a couple of other files (non update) to get information to display on the subfile screen. There aren't any calls to other programs from within this build subroutine. This program is not an AF OR Caller. This is my first time on this forum so not really sure of the best way to send code??

Are you opening the file for update? If so, maybe you are seeing some
locking issues with another program? How much processing do you have to
do on the records before writing them to the subfile? Are there any other
programs being called from within the main subfile loading loop? Code
would really be helpful at this point. Is the program in a named AG?
Caller? DAG?
Thanks

RE: Subfile initial load very slow
Thanks Alan - I've considered this. There are 2 logicals - either by name
or contract# - which ever is selected. I thought it might be only the
first time that day, but seems to happen on and off during the day.

Hi Andy
One thing comes to mind
by initial load, are you talking about the first for the day, or the first
for each user
Does the program use a logical and is that logical being built for the
first time being used that day

I've been scratching my head about this one for some time. This is an
RPG400 program. I have a subfile that is loaded from a file that only
contains 3200 records. The initial load takes a long time (over a
minute).
In subsequent calls to the same program, it responds much better (2-3
seconds). I've gone into debug - doesn't seem to hang at any location.
I've watched it process (WRKACTJOB) and it seems to do the same process. I
have looked at locked records - doesn't seem to be a problem. Can anyone
suggest other techniques for debugging this problem. As you can imagine,
the users don't like the long delay.
Andy
