Re: Using a timeout with display files

John/Daniel:

All that is already working. What I need is to know if there is a way to
enforce the system to actually read the display with what's on it if there
was anything typed in on it by the user. What I'm having now is working,
the 30-second timeout gives control back to the program, but I don't have
any modified data by the user.

I was looking after the use of the MDT indicator, but I'm not sure if when
it times out, it would turn the MDT's on and have any data back in the
program.

Thanks!!!

Javier,

Only way I know of is override the display file and then use write/reads
instead of exfmt on the display file.

My (old) example, all rpg . . .

o--------------------------------------------------------------------------
<=> - Timeout a workstations after nn period of inactivity
--------------------------------------------------------------------------
ftsusdp4d cf e workstn
f usropn
f maxdev(*file)

. . .

// Override waitrcd on the display file for shorter interval
gCmd = 'OVRDSPF FILE(TSUSDP4D) TOFILE(*LIBL/TSUSDP4D)
WAITRCD(30)';
gMsgid = utlty_RunCmd(gCmd);
if not %open(tsusdp4d);
open tsusdp4d;
endif;
- - - -
. . .
monitor;
// Write screen, wait for input
write SCREEN1;
read tsusdp4d;
on-error 1331;
msg_Completion('Due to inactivity, ' + %trimr(psds.Pgm)
+ ' auto-exited.':3);
exsr @exit;
endmon;

hth - john

Man, these tricks a so long ago - I don't remember exactly, but is it
possible, that you need to code the INVITE keyword on DDS level?

I think I wrote something similar about 20-25 years ago for the logistics
company I worked for - but I don't remember exactly how I did it - but
INVITE plopped up in my mind, when I read your mail - but I don't know, if
it is right.
