KARCM2

       INTEGER FUNCTION KARCM2 (TEXTA,LOCA,TEXTB,LOCB,LENGTH)

          This function is similar to KARCMP, except that the
 character  comparison is done without  regard to letter case
 for the letters A-Z and  a-z.  It is provided because of its
 wide utility in, for example, testing responses entered from
 interactive terminals which support lower-case letters.
