Perhaps the original poster was seeking a BASIC-like
solution. Mr Wagner, I checked some of my sources and
find no trim() function in C. I did find a RTRIM$ Function
in QuickBasic 4.5 that 'Returns a string with the trailing
(right-hand) spaces removed.' The function may exist in
other BASIC implementations.

Perhaps using a facility from BASIC is not so trivial.

Both C-style and Pascal-style strings are rather
straight-forward to implement in COBOL. BASIC-style
strings may be implemented in COBOL; but there are,
as I see it, problems with garbage collection and
compaction.
