Re: Regular Expressions and Standard COBOL (was Re: Use of Classconditions in COBOL)

Traditionally (as I recall) there were issues with the caret vs "not sign" f
or
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  translate
d
by  the 3270  emulation  program  into  the  CECP  used  by  the  MVS  syste
m.
Any differences  between  the  CECP  and  Code  Page  01047  (the  code  pag
e
used  by OpenEdition  MVS;  see  6.1,  "EBCDIC  Character  Encoding"  on  pa
ge
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
