Back in the late 80s, we had a bunch of C128s running COMAL in the computer lab in school. I was quite proficient in BASIC back then and found COMAL's structuredness somewhat narrow minded and stuffy. But then I didn't know any better, and I fortunately learned to appreciate better structured programming languages soon.
COMAL was my first programming language (unless you count HP 11C code), it was really great. Does anyone know where to get the Windows version?
That and Simon's Basic were my earliest programming experiences.
I found it in the students library and I had a C64 at the time and I thought "Wow, this is it! This is the official, real language for the Commodore, 'cos COMmodore and COMal, obvious, right?"
