I know that the question regarding conversion of strings to upper
case was asked from the turbo pascal perspective.  Here at the Univ.
of Akron, our introductory pascal class uses an IBM mainframe.  In pascal,
this means that the collating sequence for the characters is a bit different
from that on most other machines (EBCDIC vs ASCII).  The conversion routines
posted both relied upon the contiguity of the codes for the characters
a..z and A..Z.  On some EBCDIC systems, there are valid characters within this
range that should not be converted in an upcase/lowcase operation.

This is something to consider for those writing programs that might be used
in both environments.  After all, isn't Pascal code completely portable?
