   We used H Extended, which claimed only to be a FORTRAN-IV.  I've
   never seen any version of the 370 series compilers that supported
   the ".eqs." et.al. operators that guarantee ASCII collating sequence
   (on ASCII systems .eqs. is the same operation as .eq. for CHARACTER).

   I wonder if IBM ever did that after I last looked?

   When we wanted to compare individual characters on our 360 we 
   stuffed them into LOGICAL*1, which caused warnings after we upgraded 
   to H Extended.
