Running under VM/370 CE at the same time. Full consoles. Notice the different style 3270 MVS console. You can see compile/link/go on both consoles. The screenshot would be better if I didn’t use model 5 (wide) terminals for DOS/VS. Model 5 really only makes sense for the TK4- screen. You know where you might want …

Back to tk4- in VM/370 CE
I’ve been working on DOS/VS in VM/370 and now that, that works good I thought I’d return to MVS. I thought I this working on a dialed console. But I guess not. I even looked back at my log here. But it looks like I cut off the bottom of the MVS console (which would …
VM EE editor
Trying to find some info on this editor. I thought I saw somewhere, where you could move the current line and ruler from the ridiculous center to the sensible top. Maybe not? You know like just about every editor does. I mean even the bottom would be better than the middle. Good info here. I …
My COBOL compile REXX exec works!
Now that I solved my DOS/VS JCL reclen & REXX problem, I successfully created my COBOL compile REXX exec, that wraps the JCL around the COBOL source and submits it to DOS/VS. I never liked storing the compile JCL with the source. The COBOL source library should only be source, IMHO. With this program working, …
DOS/VS JCL reclen & REXX
Several things I discovered. My old REXX COMPILE EXEC…doesn’t work on VM/370CE and DOS/VS as written! I was using a newer VM and DOS, probably SP. I discovered the QUEUE statements require the string to be 80 characters. So I must pad them first. I also found that the EE editor doesn’t create fixed length …
My old REXX calendar program
Got it working on Hercules VM/370. Wouldn’t work as written using EXECIO statement’s to read/write to disk. So I changed it to use LINEIN/LINEOUT statement’s. I don’t believe these were valid statement’s when I wrote this 29 years ago on 3/31/94. It makes a calendar of the current month…by default. And flags the current day …
VM/370 CE EXECIO error
Well it certainly helps to place a working example next to your own code in error. I spotted a slight problem. Starring me in the face the whole time. Spelled it correct in the title…before I wrote this! However it still complains about the FINIS. Also I learned I could do…HELP EXECIO
VM/370 and EXECIO
I tried to copy one of my old REXX programs to VM/370 but it didn’t like some statements. EXECIO for example and I use that a lot. I assumed it wasn’t supported. However someone implemented it for VM/370. But it still failed for me. So I need to look into it. If I could find …
VM/370CE with vanilla TK4- and DOS/VS 5 pack
Trying to start DOSVS and you’re supposed to create 2 new files in DOSVS guest… Extract tk4 and move DASD to VM/370 mvs/dasd/ subdirectory Extract DOSVS and move /dos/dasd to dosvs/ subdirectory. Logon to dosvs and create… Except when I try and execute DOSIPL as documented in their write up (I used this test name …

VM/370 multiple OS guests
Today’s PC VMs have nothing on IBM who started doing this in the late 1960s with CP/CMS. VM/370 was released in 1972. I ran TK4- (MVS 3.8J) and DOS/VS under one VM/370…running in Hercules. Would anyone do this in the real world? Perhaps a school. IDK. DOS/VS is the only OS I didn’t bring completely …
