Re: Message Waiting Indicator

For a kiosk application I suggest:

****

*** Special notes concerning the auto-refresh feature. The goal is to * * have the screen be auto-refreshing on a user-selected time period. * * At the same time, we need the user to be able to interrupt the * * cycle at will. * * 1-The *DSPF must have the INVITE keyword, and if there is to be a* * subfile then INVITE must be conditioned with an indicator. * * That indicator must be off when clearing and filling the * * subfile. Tip: Use a unique indicator. * * 2-Look at the F-spec. You need "workstn maxdev(*file)" * * 3-The RPGLE program must use WRITE/READ combinations. * * --->Do not use EXFMT. <----------------------------- !!!!! * * 4-The conditioning indicator must be on when doing a WRITE/READ. * * 5-Remember the rulz: Always WRITE the record and READ the file. * * 6-Use a MONITOR/ON_ERROR/ENDMON block on all WRITE/READ pairs. * * 7- wCmd = 'OVRDSPF FILE(DQMON10D) WAITRCD(' * * + %char(%int(wMinutes * 60)) + ')'; is what makes it work.* * 8-When the screen times out, MUST set off conditioning indicator * * and then WRITE the screen again, so that the INVITE keyword * * is not active. * An example is: http://www.martinvt.com/SQL_-simple-/Dataque_Monitor/dataque_monitor.html **

I am curious as to whether or not this screen was waiting on input. Most people use EXEFMT to display screens. This is because they write some stuff out, then read some input from the user. However if you are only display kiosk information and are not waiting for user input then forego EXEFMT and just WRITE the screen as is your wont.
