Which EBCDIC code page?
Brackets (ASCII 5B and 5D) are not in the same position for all EBCDIC code
pages. The important ones are:
037
BA
BB
1047
AD
BD
I don't know where they are

What are those strange characters, "[" and "]"? What are their EBCDIC code

X**(-0.5) is more a problem when X may be negative.

C really hasn't a control variable; merely initial, final, and terminal
conditions.
Rexx has control variables, but unlike other languages they may be modified
within the loop, with well-specified semantics.
In ALGOL-68, the loop statement itself declares the control variable, which is
local to the repetitive block and acts like a constant in that it's
syntactically
prohibited to modify it.

Indeed. And a Bad Example is batch operators who "fix" programmers' coding
errors to do the favor of sparing a turnaround latency.
