How to read a file with RECFM=U in MUSIC/SP?

 

How can I read a file with RECFM=U in MUSIC/SP?
Unfortunately, using Waterloo C is not possible (see for ex. https://www.canpub.com/teammpg/de/sim390/watc_help.htm).
I have also tried using REXX but to no avail (see for ex. "The MUSIO command in Rexx" in the rexx help file).

I think I figured out how to do this once but it was a long time ago and
I don't remember the details. Maybe calling subroutine MFIO with
type options set to something like 'UIO RD.' might be the way to go?

Try looking up MFIO in the administrator reference manual eg: MANX AR MFIO
if you have the online manuals installed.

I don't know if it is possible to call MFIO from Waterloo C, it might be
necessary to call it from FORTRAN instead.

It has to be possible with the assembly language interface too using
MFARG / MFGEN / MFREQ and friends but I don't know how exactly. There
should be something about this in the administrator reference manual too
if you want to go that way.

In the WATC?help file it talks about calling assembler. Seems that you could code up an assembler module to read/write to RECFM U.

I assume you want to read a load module ... why do you want to read the load module,
what information do you want to get from there? Maybe there are other (simpler) ways
to do what you want to do .... ???

We could probably help you more if you tell us more about the problem you want to solve.

Kind regards

Hallo Bernd,
?
Here some info on how I come to the idea of reading a dataset in RECFM=U?
?
I have recently learned HLASM and as a hobby I am implementing some old ProjectEuler (https://projecteuler.net/) solutions in HLASM.
I start from a solution in C and implement it in HLASM (the solution is implemented as a main program in C that call an HLASM function).
I have the code on PC where I edit it using Codium (it has a good plugin for HLASM). Then I copy it to the target system via WinSCP.
The target systems at the moment are z/OS (under USS), TK4- and MUSIC/SP.
So I download and upload a lot of files/datasets from here to there and .... :-)
Usually it is just source code. But sometimes also already compiled programs.

I happened to copy one of these programs between two MUSIC/SP systems and noticed that it no longer worked.
?
So, I have temporarily set aside the ProjectEuler solutions and moved on to this (hobby) problem:
? "Read a dataset with RECFM=U and hexdump it".
?
My results in my target systems (z/OS, MVS3.8j and MUSIC/SP) are following.
? - z/OS ? ? : trivial when done in C from USS.
? - MVS3.8j ?: very simple and done in C using the JCC compiler
? - MUSIC/SP : still not solved (tried with Waterloo C and Rexx)
?

Is my earlier suggestion completely without merit or
or can nobody (who uses gmail probably) see my posts
or what?

I've seen your post :-)
?
Only seeking to learn new stuff, I checked the MFIO interface documentation and took a look at the example $SUB:MFIO.SAMPLE. I was able to open/close a file with MFACT and read records from it with MFIO, via a Fortran G program. I have no idea how to do it in Waterloo C. I haven't check with RECFM=U since I can't find a file with that record format. The .OBJ are 80FC while the .LMOD are 128F.? In the end, I think your suggestion is good.
