RE: [U2] [UV] Basic Program Scheduling Priority
The RQM statement has not appeared in any universe documentation at least as far back v6. I actually had to locate some old prime manuals to find out what this was statement was all about. I recall reading some blurb somewhere that although RQM is still supported by the universe compiler it is in effect a NOP and doesn't actually do anything on any platform.

On UniData, the documentation for RQM includes the following: " RQM is a synonym for the SLEEP function. For more information, see SLEEP." If you check TIME() or SYSTEM(12) before and after an RQM statement, you'll see that, without any parameters, RQM will generate a SLEEP 1. Although not documented as such for UniVerse, this will act the same way. Years back, I was working on Sequoia Pick O/A and was looking into a program that was suddenly taking a long time. I came across a bunch of RQM statements and talked to the programmer who was working on the program to see what they were all about. He said that they forced a screen flush so a record counter would be up to date. I slapped together a small test program and demonstrated that this was actually doing a one-second sleep, which was happening pretty frequently. (Well, yes, it did flush the screen, too.) I replaced all of the RQMs in the program with CRT CHAR(0):, which forced a screen flush on O/A, and the program sped up drastically. So anyway, this shouldn't be treated as a NOP. If you come across something like this in a program, get rid of it, unless the desired effect is actually to sleep for a second. I can't speak to other platforms, but for Pick O/A, UniData, and UniVerse, that's what you'll get.

RE: [U2] [UV] Basic Program Scheduling Priority
Thanks to everyone for their suggestions. The CHAP command was exactly what I was looking for (thanks Martin and Ray). Many years ago I had used the General Automation R91 BASIC statement CHAP and actually had looked in the UniVerse BASIC manual for it. It never occurred to me to look for a UniVerse command-line equivalent. I will give it a try. BTW.. Does anyone know how to tell if a process has been CHAP'd up or down? CHAP does not appear to return anything of value to tell you about what it has done. ??? Thanks again!

RE: [U2] In-Line prompting AGAIN
> SELECT CUSTOMER <> WITH FLAG There is probably an item called "7", but not one called "31" in either DICT CUSTOMER or VOC. Put the quote marks outside the prompt text. SELECT CUSTOMER "<>" WITH FLAG The 1st way will prompt (the quote marks literally appear): "ENTER CUSTOMER NUMBER "= the 2nd: ENTER CUSTOMER NUMBER = The 1st will execute: SELECT CUSTOMER 7 WITH FLAG the 2nd: SELECT CUSTOMER "7" WITH FLAG --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/
