Apparently I added WRK141.141, WRK142.142 and four cbt volumes to tk4- (MVS) and didn’t document it. From their FAQ “The CBT tape is a collection of freeware almost all open-source distribution for the IBM mainframe MVS and OS/390 operating system environment.”

Making YouTube videos
Made YouTube videos about Hercules MVS mainframe coding locally. Made them for myself posted privately, but may make them Public. Have another in mind. Using virtual tapes to load large amounts of data into MVS. Both of these topics were personally important to me! I’ll do Mainframe emulation for a while then stop long enough …
maketape/tapedump updates
While googling “Hercules AWS ” I see that Jay Mosley made some updates in July 2020 that I was unaware of. Changes seems mostly concerning using gnuCobol to provide a fullscreen interface…interesting.
Hercules virtual tape – large datasets
These are timings for a large one million customer records, dataset. It follows the same process below. It just goes to show my reasoning why I like this method to move large datasets to the virtual mainframe. Use maketape to create the virtual tape file! bill@bill-MS-7B79:~/Mystuff/Mainframe/MVS/JCL/TAPEDASD$ time ./maketape INPUT: customer-million.txt VOLSER: VOL001 DATASET: CUSTOMER.FILE OUTPUT: …
Hercules virtual tape review
Previously, I talked about Hercules virtual tapes without being specific. I find this useful for getting large amounts of data to a MVS dataset. So here I find myself reviewing/documenting the procedures…again! These below examples are using test data with a fixed length of 165 characters! Getting the data It seems I created some fixed …
I’m on a roll with problems (3270)
So I started MVS in hercules mainframe emulator on Manjaro. Went to start a x3270 terminal. It did not exist…no problem I’ll just install it. So I installed it. But it said it required a restart. Hardly anything requires a restart. Ok I need to try and shutdown MVS manually. Found manual said something like …
x3270 wide screen
I hadn’t played with mainframe emulation for a while, and I was reviewing my notes. So I started up MVS using the TK4- package. I then used the x3270 terminal emulator to get a TSO/ISPF session as I always did by typing “x3270 127.0.0.1:3270” and as usual I found viewing 132 column listings tedious [PF10/PF11 …
enscript with greenbar output
The following commands are taken from a link Professor Rene’ Ferland’s pointed to on his website. enscript –font=Courier-Bold@8 -l -H3 -r –margins=25:25:40:40 -p cobol01.ps cobol01.cob ps2pdf cobol01.ps cobol01.pdf The professor’s script used Ghostscript rather than ps2pdf. The above 2 commands can be combined into one. enscript –font=Courier-Bold@8 -l -H3 -r –margins=25:25:40:40 -p – cobol01.cob | …
Greenbar and enscript
I asked a question about a YouTube video I watched “Using Cobol and VSAM on DOS/VSE – M174” concerning greenbar listings shown, and Professor René Ferland, the video author, responded that it was created using his script that uses enscript. I’ve never even heard about this program or the Adobe program it’s based on, and …
Master the Mainframe course…thoughts
I thought this was a good intro into z/OS. I had been playing with MVS on Hercules, and I wanted to have some idea on how MVS and z/OS differed. Is MVS so old that I’m wasting my time learning it? Other than obvious improvements over the years, I found the biggest differentiator is the …
