Nah-Nah-Nah-ne-boo-boo! Ha! PDP-4! With 64KB RAM! 5MB Winchester drive, and booted from tape!
I also worked with 360 system Assember, on IBM minis running 360OS (remember the "green card?" The only JCL command I can remember is balr). From there, I went to FORTRAN, then on to C, and left the programming side in about 1989. I've been doing PC system installation, repair, and networking ever since. I became a Novell instructor for 4 1/2 years, and I'm a Master CNI (instructor, or was, until they retired the certification), and hold 4 different Master CNE certs. But I've got to forget about keeping that up, in order to get up to speed ASAP on Microsoft products. Because MS is selling, while Novell isn't, even though Novell's got some of the coolest stuff around.

Wasn't BALR the "Branch And Link Register" 360/370 assembler command and not JCL?
