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 […]

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 […]

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 […]

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 […]

I’m not a put myself out there kinda guy. Also since I tend to have a lot of sinus problems, my already pretty bad speaking voice is even worse by my sniffing and throat clearing. But I want to make another YouTube video. These are Hercules MVS (Tk4-) vids. I have no desire to be […]

Tried to install x3270 today…and it doesn’t exist in their repositories anymore! As a matter of fact, no 3270 emulator could be found. I thought Arch had everything? Maybe the writing was on the wall, the last time I installed it on Manjaro recently, it was in a foreign language! No love for mainframes? Just […]

Wrote new python program to copy local files to a MVS PDS by wraping IEBUPDTE JCL around the file.

If you have to restore TK4- for some reason. You still have all your programs/JCL! Sometimes if there are problems it’s just easier to unzip TK4- and start anew!

I have been using compile/go JCL to run my COBOL MVS programs, since that was the JCL I found used for other things. Since I mentioned in a video that the execution speed of a JOB was not a true indication of speed, because in addition to the execution, the program was compiled every time. […]

Since I like to develop MVS programs locally (on Linux)…for my purposes I find it easier to use a IBM utilitiy to move PDS members to/from the mainframe. As a former VM/VSE systems programmer with no great desire to be a MVS systems programmer, this might be a good way to run jobs on a […]
