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 […]
Another 3270 terminal emulator
Just to be complete I thought I’d mention another freely available 3270 terminal emulator on Linux. I briefly tried the c3270, 3270 terminal emulator, it is easy to increase/decrease the font size simply by pressing <Ctrl>+ or – respectively. The thing that wasn’t readily clear to me was how to use special keys such as […]
x3270 Terminal Emulator fonts
I really needed larger fonts for the Master the Mainframe course. I used the default x3270 many times using the Hercules emulator but for some reason the smaller font really bothered me in this course. Watched “Setting up x3270 on Linux”, a YouTube video where a guy installed with apt then easily changed the font […]
gnuCOBOL and IBM COBOL
I should add that using many of the features of gnuCOBOL may also help familiarize me with IBM COBOL advancements because as stated in the FAQ…GnuCOBOL implements a substantial part of the COBOL 85, COBOL 2002, and COBOL 2014 standards, as well as many extensions of the existent COBOL compilers. And the COBOL versions that […]
Greenbar, almost done?
I changed the first print line to start lower on the form for better looking alignment. I also finally figured out how to use the python module PyPDF2 to crop a little off the left side of the form (thanks to a YouTube video) for better symmetry as well as removing the pesky 1st blank […]
UNPK and ED
After reviewing the above two S/370 Assembler instructions. I guess I’m wondering why you would use UNPK which unpacks packed numbers into zoned decimal digits which aren’t necessarily printable. ED on the other hand can also can also unpack packed numbers into zoned decimal…but these are printable. I guess I knew at one time but […]
More S/370 Assembler
Watching myself stomp all over storage as I re-familiarize myself with IBM mainframe Assembler. Playing with simple packed and register arithmetic. I really like the SNAP macro for looking at registers & storage.
Assembler MVC basics
Playing with S/370 assembler specifically the simple MVC instruction. Realized I’d forgotten basics by examining storage with the SNAP macro, after trying various moves. Came to realize that the length is only determined by the first operand. Verified this later by looking at yellow card. Figured out one way to move values to a 80 […]
