RedHat 9 (Linux i386) - man page for lsame (redhat section l)

LSAME(l)		      LAPACK auxiliary routine (version 1.0)			 LSAME(l)

LSAME(l)				   BLAS routine 				 LSAME(l)

NAME
       LSAME - return .TRUE

SYNOPSIS
       LOGICAL FUNCTION LSAME( CA, CB )

	   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 com-
	       pared.

	       Test if the characters are equal

	       Now test for equivalence if both characters are alphabetic.

	       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.

	       ASCII is assumed - ZCODE is the ASCII code of either lower or upper case 'Z'.

	       EBCDIC is assumed - ZCODE is the EBCDIC code of either lower or upper case 'Z'.

	       ASCII is assumed, on Prime machines - ZCODE is the ASCII code plus 128  of  either
	       lower or upper case 'Z'.

	       RETURN

	       End of LSAME
