I watched a Moshix video where he’s offering a print service for hercules/MVS. He pointed to a video from the guy who wrote the greenbar program, who he partnered with for his print service. His YouTube channel is Mainframes & More with Matthew. This particular video is here. The program source is here. The only …

Pushed my 1st real Go program to GitHub
I wanted it on GitHub if for no other reason than to have a official date associated with my first real Go program. Also to add some activity and diversity to my github. There’s Cobol (mainframe & gnu), Basic, Python, Julia and now Go! Maybe I should add Lazarus/Pascal too. I could have also posted …
Rewrote a Python program in Go!
I rewrote the bulk of my Python parse the local Tk4- prt file in Go. I thought it would be easy but it took me all day. Then again I don’t exactly think in Go at this point. It won’t win any awards for Go style and technique. It needs to read the prt directory …
Hercules version
I guess I never noticed or looked. But Tk4- uses Hercules version 4. The main Hercules page says the current version is hercules-3.07-1. There is a version 4 manual available with an date of November 21, 2015.

Hercules/MVS (tk4-) on Tumbleweed
TK4- runs fine on OpenSuse. The 3270 emulator (upper right) works as expected, menu items in English as opposed to the last time it even worked in Manjaro. With OpenSuse’s connection with mainframes I think 3270 emulation will be available for a while. Not to mention that OpenSuse itself actually offers Hercules.
Assembler/REXX
Maybe with all the trouble Rexx is giving me I should go back to something easier like Assembler 🙂 Was the Rexx developer trying to look like he wasn’t using other peoples ideas? I mean really…EXECIO. Execute I/O I guess. I guess I’ll just let it process in the background, until I have a Eureka …
REXX
Just installed BREXX on TK4-/MVS. Now to read the manual! As they say…back in the day, I wrote many REXX execs in VM/CMS. Our shop used CA-Vollie, which was a VSE, ISPF like environment. I assume that, it’s been so long, I can only guess that, that’s what it was modeled after. It was a …
Assembler Disk to Print
Successfully fixed Assembler Disk to Print program I had typed in week or so ago. Was having problems with DCB macro. More specifically line continuation. Almost asked for help in the MVS forum. Finally solved by editing in VS Code and realize my source alignment was off by using the visual guides. It was a …
Making YouTube videos and learning
I mentioned before that one cool aspect of making a YouTube video to perhaps explain something to others is that I often find myself learning more on the topic than I knew. And once again after working on a video to explain how to create a MVS stand alone executable, I found myself digging in …
Copy a PDS to another PDS
Thinking about this new YouTube Video and thought maybe it would be more useful to others to do it on a 3270 using ISPF. Which I assumed would be intutitive…but it wasn’t. See the copy utility below. It wasn’t clear to me how to copy looking at this panel,from the beginning, after I decided I …
