| Traditionally (as I recall) there were issues with the caret vs "not sign" for
IBM mainframe shops (that used PL/I - and did some workstation development). I
don't recall all the details, but do recall SOME cases where these two were used
to equate with each other.
At
http://www.redbooks.ibm.com/redbooks/GG244473.html
there is a section with the following information:
"Characters entered at a non-3270 workstation are normally translated
by the 3270 emulation program into the CECP used by the MVS system.
Any differences between the CECP and Code Page 01047 (the code page
used by OpenEdition MVS; see 6.1, "EBCDIC Character Encoding" on page
39) need to be allowed for. In our case the CECP used was
U.S./Canada Country Extended Code Page 00037. There are four
characters with different representations. They are:
· Left square bracket ( [)
· Right square bracket (])
· Circumflex (caret) (^)
· Not symbol (Ø )"
I don't know if this is "useful" or not
