13.3.2 HEXDCI

1.

Function

Converts a character string expressed in hexadecimal into a bit pattern.

2.

Call

CALL HEXDCI(CP,IP)

3.

Explanation of Parameters

CP	(C*(*))	A character-type argument that specifies the character string expressed in hexadecimal as a combination of '0'- '9', 'A', 'B', 'C', 'D', 'E', and 'F'.
IP	(I)	An argument of 1 word length that returns the bit pattern.

4.

Notes

(a)

When the length of CP is N (=LEN(CP)), then this subroutine checks the lower MIN(N,NB/4) characters of CP (NB is a number determined by the internal variable 'NBITSPW') and returns the pattern right-aligned. When N is greater than NB/4, this checks the pattern of the lower NB/4 characters (CP(N-NB/4+1:N)).
