+      LOGICAL          FUNCTION LSAME( CA, CB )

+*     .. Scalar Arguments ..
+      CHARACTER          CA, CB
+*     ..
+*
+*  Purpose
+*  =======
+*
+*  LSAME returns .TRUE. if CA is the same letter as CB regardless of
+*  case.
+*
+*  Arguments
+*  =========
+*
+*  CA      (input) CHARACTER*1
+*  CB      (input) CHARACTER*1
+*          CA and CB specify the single characters to be compared.

+*     .. Local Scalars ..
+      INTEGER            INTA, INTB, ZCODE

+*     Test if the characters are equal
+*

+*
+*     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 )

+*
+      IF( ZCODE.EQ.90 .OR. ZCODE.EQ.122 ) THEN
+*
+*        ASCII is assumed - ZCODE is the ASCII code of either lower or
+*        upper case 'Z'.

+*
+      ELSE IF( ZCODE.EQ.233 .OR. ZCODE.EQ.169 ) THEN
+*
+*        EBCDIC is assumed - ZCODE is the EBCDIC code of either lower or

+*
+      ELSE IF( ZCODE.EQ.218 .OR. ZCODE.EQ.250 ) THEN
+*
+*        ASCII is assumed, on Prime machines - ZCODE is the ASCII code
+*        plus 128 of either lower or upper case 'Z'.
