Saw this in the Mainframe Enthusiasts Discord. Very interesting! Here is the announcement letter. Minor point…I’m happy to see it simply called TK5 and NOT TK5-. I always found the “-” annoying.

GCSORT
I heard about GCSORT on Moshix’s YouTube Channel titled “Sorting with GnuCOBOL Sort”. What I don’t exactly understand is it’s association with GnuCOBOL. It’s even described in GnuCOBOL’s FAQ as “A powerful external sort utility, for use with sequential (fixed length record) files.” Perhaps it’s because… GnuCOBOL already has a SORT built into it. I’ve …
VM/370 and EXECIO
I tried to copy one of my old REXX programs to VM/370 but it didn’t like some statements. EXECIO for example and I use that a lot. I assumed it wasn’t supported. However someone implemented it for VM/370. But it still failed for me. So I need to look into it. If I could find …
TRS-80 Color Computer
This news is 2 months old (Version 2.5) however I just found out (by poking around his discord channel) that George Phillips TRS-80 Emulator now includes the Color Computer. Pretty cool. t80gp -mc -mem 4 -l1

VM/370 multiple OS guests
Today’s PC VMs have nothing on IBM who started doing this in the late 1960s with CP/CMS. VM/370 was released in 1972. I ran TK4- (MVS 3.8J) and DOS/VS under one VM/370…running in Hercules. Would anyone do this in the real world? Perhaps a school. IDK. DOS/VS is the only OS I didn’t bring completely …
Submitting jobs to DOS/VS IN VM/CMS
Looking at running DOS/VS under VM again. First off I wanted to know how I started VM with 4 guest terminals setup. As I showed here… OK I made things difficult for myself because I documented things multiple places. And they don’t all work. All this revolves around the “MECAFF – tools”. This also give …
YouTube Upload Date
Concerning my old YouTube video “Working on Hercules MVS programs locally”. I changed the comments and visibility from Private to Public and YouTube changed the date on my old 2.5yo videos to todays date. I don’t like that. Because they’re not exactly current. Although TK4- hasn’t changed. The videos themselves have not changed. As you …
