Hi, interested to move some old Rexx stuff onto CE and WAKEUP function is missing (I think). Has anyone stood up an emulation or close alternative. If not, I guess I break out the assembler.....
|
The VM/370 Community Edition supplies a WAKEUP server that uses a control file to drive REXX routines at specific times. Event handlers can be driven: - at specific intervals from "Now" - on specific dates or date patterns -on specific?days of the week or on weekends
The code is on the 191 disk of the WAKEUP virtual machine.

Hi Bob, Yeah I am aware of the server. It runs with just sleep though, and I was wondering about the WAKEUP MODULE that could be at the heart of this server. I know that WAKEUP MODULE is a SP(?) or later version facility.
|
The IBM WAKEUP facility was part of the copyrighted IPF Program Product. I believe it became?available in the VM/SP timeframe.
The source for the DMSLFN program is in the VMSETUP?CMS search order on MAINT. It shows what other capabilities are available to the WAKEUP?server, besides the timer facility. It might be possible to add whatever additional capabilities you are interested in. Bob

This is going back a long way, but when DOE started putting
information on the internet, we got a program called GOPHER,
written in Rexx and used either WAKEUP or a replacement YWAKEUP.
Since we already had WAKEUP, we ignored YWAKEUP except to see that
it was supposed to be a NON-IBM replacement. I don't remember who
wrote it. Maybe someone else in here or on the VM list remembers
it better, or maybe even has a copy.

I recall using WAKEUP or YWAKEUP (don't know which of the two)
to implement a plotter server. The plotter server was used to read
incoming plot files,
stored them and after a certain time period, plotted them on a
large piece of paper
on a large electrostatic Calcomp plotter. The plotter server moved
the graphics on
the paper so that the paper was used as economical as possible
(the graphics had
different formats).
So the WAKEUP routine in our case woke up on arriving RDR files
(which were handled
without delay) AND on elapsed time periods. IIRC, we received a
return code from
WAKEUP which telled us which event triggered the wakeup.
HTH, kind regards

A VM370CE server using the?WAKEUP REXX function package can wait on a timer, reader file arrival, or command sent by SMSG. Other event types could be added.
Bob?

OK. Good shout Bob. That is a great work around for me. I'll put the assembler away.
|
A open-source WAKE MODULE came out in the 1980s, with a similar function to WAKEUP.? I have the source, it might to be off the 1991 VM Workshop tape.? I don't know if it depends on VM/SP CP.

Hi Drew, I scanned the tape named 91VM.AWS but I don't see it. If you send me the source, I will look at adding this to the next VM370CE release. Bob

Happy to help out with code needs a fix. Warmed up the Assember recently but not needed. Haven't felt the joy of a successful "BALR" in too long :-)

Drew sent me a copy of the WAKE assembler program he mentioned. It appears to be coded using VM/SP system macro interfaces and the NUCXLOAD command which is not available to VM/370. The latter is not available to VM/370 because the program loader cannot process a? relocatable MODULE. WAKE and WAKEUP both implement: 1. Waiting for a specific time (and date) 2. Waiting for a command issued with SMSG. 3. Waiting for a reader file to arrive.
I removed the support, originally added to my version of WAKEUP, for IUCV and CONSOLE macro capabilities that don't exist in VM/370. I can send a copy of WAKE to anyone who wants it, but I suggest you use the WAKEUP REXX function package, which is already installed. To produce an assembler listing, so you can look at the WAKEUP code: LOGON MAINT VMSETUP?CMS VMFASM DMSLFN DMSLCL
That produces an assembler listing file you can examine.?

On the 1986 Workshop tape, 86WTTL.AWS, file 132, 132?? Steve Howes, Brigham Young Univ.: VM mods to spooler, tools contains a WAKEUP ASSEMBLE. There are many other files in that one, and they are all LRECL 1024 RECFM F, which rings a bell, but not clearly. (Some kind of LOAD/UNLOAD?) I have placed all of those files on one tape, /g/h390-vm/files/1986%20VM%20Workshop/2022-01-13.86WTTL.FILE132.het as I can't actually read any of them on my VM/370 CE system, to determine how they are related. If this is not useful, please let me know, and I will delete it. ?... Mark S.

From distant memory an lrecl 1024 sounds like a text file in compressed format from vm/sp? so you will need to get something to decompress it on earlier versions. eddy_balem

Mark,
F 1024 sounds like a packed file.? COPYFILE fn ft fm (UNPACK? might restore it to F 80.

I expect the F 1024 file was created in COPYFILE ( PACK format, BUT the block size
indicates that it was created on a VM/SP or later version of VM. The PACK format
changed to F 1024 when the enhanced CMS file system was introduced with disk block sizes of
512, 1024, 2048, or 4096. In VM/370, the COPYFILE ( PACK output is F 800, so VM/370
CMS doesn't recognize it and cannot unpack the file.

Is the “pack” format documented anywhere? ? Dave ?

If the file looks scrambled/compressed perhaps its in Terse Form which IIRC uses a 1024 blocksize.
