   Although we had OS/360, we were using IBM FORTRAN H Extended
   Enchanced from a 370.  (I assume one of the compiler flags told
   it to generate only 360 compatable code.)

   That, and the compiler on our Xerox Sigma 7, are the only places
   I've ever seen Hollerith constants in anybody's code.  I think
   both of them allowed Hollerith constans in assignment statements.

   What drove me nuts, when porting code from the IBM to VMS, was all
   the places where character strings had been encoded as the hex values
   of the EBCDIC characters.  Had to look up the EBCDIC characters, then
   replaced them with quoted strings which all our compilers were happy
   with.
