About Us


CLE is an aspiring software company. Collectively, my associate and I have over 40 years of mainframe software development experience, Since mainframe software is not exactly a retail commodity, we decided to try our hand at software for Windows (CE and desktop). Someday we would like to add Linux to the list.

I discovered Hercules in the Fall of 2006. I tried it out using systems I had some experience using like the ASP MVT release and the Turnkey MVS 38j release.  After "unlearning" so many of the new features of OS/390 and ISPF that I have come to use by habit, I began to see the full potenital of Hercules. I also realized how much of the console operations I forgot.

I started programming IBM S/360 back in 1969 - in the days of the 'open' shop.  A room full of hardware, hands on access to the system - punched and ran my own card decks, took my own paper off the printer, mounted tapes and disk packs in the "pizza oven" (2314 drives). There was no TSO. 

The "shop" actually had two CPUs. One box (360 mod 50) ran OS/360 MFT by day and DOS/360 by night. MFT was run during the day to support a revolutionary new product called CICS. Dozens of teletype machines were tied into the system. The other box (360 mod 40) ran DOS/360 most of the time but we could run MFT on it. It's primary job was to be a backup to the mod 50 so the online network would have 5x10 availablity.

I moved on to a shop in 1974 (as a consultant) that run twin s/360 mod 65s. BIG iron in its day running Os/360 MVT. Several hardware upgrades took place here - new 3330 replace 2314 and S/370 168 replaced S/360 65. Still running MVT. I left and came back 5 years latter and they still were running MVT!

In 1979, kicking and screaming all the way, the shop was being forced to upgrade to MVS. VM/370 was installed to keep production and testing with MVT going. This allowed MVS to be implemented. The biggest problem with the MVT to MVS conversion was the number of patches, fixes and enhancements made inhouse to MVT. Much of the inhouse developed software depended on some the these patches. Therefore, all of these patches had to located and changed to be MVS compliant or to use exits.


Over time, I have accumulated a lot of stuff, which I was about to put in the recycle bin where it seemed to be the most valuable. 

Since I discovered Hercules, I think some of this stuff may be of interest to others and as time permits, I will try to resurect some of this stuff.
