Can someone please change the topic of this thread? No longer about for-else.

Or some terminals provided [ ] but not { } <G>
Modula-2 appears to have fixed on (* *) for comments, and only [ ] for
indexing.
Consider the potential mayhem going from a language where { } are
comment delimiters to one where they are block delimiters <G>

My college mainframe used EBCDIC, but the available languages did not
include C or Pascal. We had APL, FORTRAN-IV (in full separate compilation form,
and FLAG [FORTRAN Load and Go] which was a "all in one file, compile & run"
used by first year students), COBOL (74?), BASIC, SNOBOL, Meta-Symbol and AP
(both assemblers, though Meta-Symbol could, provided the proper definition
file, generate absolute binary code for pretty much any processor), and
something called SL-1 (Simulation Language-1, which produced FORTRAN output for
discrete event models).
UCSD Pascal, and PDP-11 assembly were run on a pair of LSI-11 systems.
Assembly used for the operating system principles course.
I didn't encounter "real" C until getting a TRS-80 (first as integer
LC, then Pro-MC), along with Supersoft LISP (on cassette tape!). (I had books
for C and Ada before encountering compilers for them)
