For some reason a old YouTube video “Create stand alone executable COBOL programs using private Partition Data Sets on MVS in Hercules!”, I created/uploaded a few years ago (7/8/2021) was private. I think it’s useful, because most of the video I see about running programs on MVS, include the cycle of compiling/running… every time. However …

Recreate my TK5
OK, maybe I’m better off than I thought. I just installed the complete TK5 update 2. After running grep to look for WHB001 (my personal DASD), I found a copy in directory mvs-tk5-old. So I copied it from there to my new current mvs-tk5/dasd/. Also, saw WRK142.142 (I don’t think I’m using it in TK5) …
TK5 – I did something really stupid
Went to apply update 2. So like always, I wanted to backup first. And by backup I mean zip the whole current directory with my DASD. But I saw there was already a backup. So I renamed the old backup. But then I forgot to do a new backup, and I applied update 2. How …
TK5 update 2
Wow, I’ve really been out of the mainframe loop. Released 12/15/2023… over 3 months ago.
GnuCOBOL state control break works
Baring a few small errors. So it reads one million customer records and creates a customer amount total by state. Some small errors. Here’s a few lines from the report. I wrote a quick Python program to count states that I hard coded and can confirm that the customer counts match. I checked a few …
Report Writer error.
OK, the working MVS version (see below) was a better starting point. I’m getting a single error. However, as you can see, it is defined at the very next section below it. I double checked my run-book that has that program, from 1977. There are similar statements that were not flagged I really hoped it …
GnuCOBOL Report Writer
Looked at an old GnuCOBOL Report Writer program, I wrote. Which was a re-write of a school assignment. It didn’t compile. I need to look into it, I assumed it worked at the time. Although it was written before the feature was included by default… I think in version 3. OK, reading this, I think …
GnuCOBOL – On Size Error
Because of my research into the state population problem, I decided I needed to alter some old GnuCOBOL control break programs, to summarize the number of customers by state. These programs kept triggering On Size Error, no matter how high I bumped the picture clause. . I remembered I assumed it was a bug. However …
VLC pause gripe
This has happened for a while. I pause a video… when I unpause it, it studders for several seconds. If someone is talking I may miss some point they’re making. So I usually have to go back several seconds so it will studder over something I already heard.
Console train
Keith Galli a Computer Scientist who makes YouTube videos, posted the “sl” command on X. I thought it was cool, so I made my own short video. How clever is that?
