-* Test if the characters are equal
-*
- LSAME = CA.EQ.CB
- IF( LSAME )

-* Now test for equivalence if both characters are alphabetic.
-*
- ZCODE = ICHAR( 'Z' )
-*
-* Use 'Z' rather than 'A' so that ASCII can be detected on Prime
-* machines, on which ICHAR returns a value with bit 8 set.
-* ICHAR('A') on Prime machines returns 193 which is the same as
-* ICHAR('A') on an EBCDIC machine.
-*
- INTA = ICHAR( CA )
- INTB = ICHAR( CB )
-*
- IF( ZCODE.EQ.90 .OR. ZCODE.EQ.122 ) THEN
-*
-* ASCII is assumed - ZCODE is the ASCII code of either lower or
-* upper case 'Z'.

- IF( INTB.GE.97 .AND. INTB.LE.122 ) INTB = INTB - 32
-*
- ELSE IF( ZCODE.EQ.233 .OR. ZCODE.EQ.169 ) THEN
