Watching this video was great! But it really drove home why the advent of Lisp Machines and Smalltalk were so radically revolutionary in their day. Today, I thank my lucky stars that I have a wonderful Lisp environment to live in. The video reminded me to thank the computer gods...

Wow. I learned how to writer Pascal programs on VAX/VMS systems at my university as my computer science major. Later I switched to C/C++ programming after my graduation.

I did a lot of programming with Borland Pascal (and other compilers), but my introduction to PASCAL happened in the Faculty/Graduate TN3270 job entry room for the Amdahl. There was a grad student (like me) from Jaipur who would nap on the bench (after Midnight) waiting for the next run of her PASCAL program to print out. *I didn't know PASCAL,* but when she got stuck, I would look at her code logic and ask her questions ... until she would see how to fix it! That would be 1984. :^)

goto in Pascal??? Ah, what the sacrilege!!! Just joking, thanks for the very interesting video! Also, I'm very glad that you went with Rob Prins TK, I was promoting his work for the long time (not that anyone listens to me, but still...) I had a lot of health issues (old fart me), but I hope I'll be back online soon promoting your channel and MVS/TK. All the best, my dear friend and teacher!

Just starting to watch, but I am absolutely flabbergasted that a tape from Way Back Then is still readable! Apparently without error. Yeah, IBM really did make solid iron.
@mieszkogulinski1687 ай бұрын
Tapes are estimated to be more reliable than hard disks over long time - modern archival tapes are estimated to work at least 30 years from date of production.
@moshixmainframechannel7 ай бұрын
@mieszkogulinski168 yes but he problem will be to have devices that can read those tapes in 30 years. Find me a device that can read a tape from 1994, and an operating system and drivers that can use that device.

Holy Smokes! This takes me back more than 50 years! I see you operating a virtual mainframe from a modern workstation. How do you tolerate the massive slowdown in factor going so far back in time? I remember working for IBM, and I do remember their mindset as being that theirs is the only way. But I also remember the 1980's jolting IBM into using 3rd party chips and software.

I loved PL/I. Pascal confused me at times due to the concept of "statement ending" vs. 'statemen separating" things. I kept putting PL/I semi-colons where they didn't belong.

Luckily I learned pascal before PL/1 so for me this wasn’t an issue

@NineInchTyrone wasn’t widely available. It’s a big language. Difficult to write compilers for it. Poor I/O capabilities. library too mainframe specific (like the ON conditions)

Never did Pascal on a mainframe. Started with Tiny Pascal on the TRS80, then Waterloo Pascal on a SuperPET for comp sci classes, then Turbo Pascal on cp/m and pc’s. MODULA-2 was supposed to take over , at one time…

I did some Modula-2 but without the LILITH machine it wasn’t going to be any fun
