Re: EXFMT with a timer

["Scott Klement" <infosys@xxxxxxxxxxxx>]

Hi Chris,

You may be able to make this work just by adding an OVRDSPF to
your program...   something like:

OVRDSPF FILE(xxxx) WAITRCD(30)

You'll then have this timeout on every screen in that display file,
however, which may not be what you want.


What I prefer to do, in these situations however, is to attach a
data queue to the screen, and then wait for data on the data queue.
Its more flexible, and allows the program to respond to more
different events than just the timeout.

This is a bit more work to program, however.  You need to:

1) Put the "INVITE" and "FRCDTA" DDS keywords into your displayfile.
2) Create a data queue with a rec length of at least 80 bytes.
3) Use OVRDSPF to attach the data queue to your screen.
4) do a "WRITE" to your screen to make it display.
5) Wait for data on the data queue.  You can specify a timeout
      value of 30 seconds waiting for data, or you can specify a
      timeout of -1 to make it wait forever. (so each screen can be
      waiting a different amount of time)
6) Check to see if you got data from the data queue from the screen
      (or possibly from another source, if desired)
7) If you did get data from the screen, do a READ to load whatever
      the user typed.

If an example would be helpful, let me know...
