I liked Seymour comment about ISPF and Xedit... In a new Super Mainframe Modernization we will need to use Visual Studio Code? Ohhh gizzzzzzz

We all had to program in lots of different languages and maybe not having the same assembler record as Seymour, I remember asm-f, asmh, hlasm, masm and ALP for sure. The difference is that C and C++ are just work, but for me, Prolog, Rexx and NetRexx are actually a joy to program in. It is not for no reason that Rexx has a Rexx Language Association. Where I draw the line is when reading an article full of misconceptions and falsehoods, that is intentionally picking on another language, which I happen to like. It could have just been: “I like Python and at long bloody last it runs more or less on z/OS. Huzza!”. No, it gives us falsehoods and irrational line of argument, and then professes not to knock Rexx, which is about the 9th lie (I do not count more than one per paragraph). Have your Python and be happy with it. Don’t knock Rexx and at the same time hobble the careers of young people and tell them now they have to learn less to be proficient on the platform. No, they now need to learn a lot more. To be fair, I am enormously grateful to the person that ported Git to z/OS - thank you! I don’t mind there being some Python in it.
