Behavior of the for-else construct

[Schachner, Joseph]

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)
