*NAME: BITLIS AUG. 28, 1989 *CLASS: data display *CATEGORY: *PURPOSE: To display bit pattern for byte, integer or longword integer scalars or vectors. *CALLING SEQUENCE: BITLIS,A,B *PARAMETERS: A (REQ) (I) (0,1) (B,I,L) Input scalar or vector B (REQ) (O) (1,2) (B) Output vector or array of 0's (off) and 1's (on) representing bit patterns of input vector A. *EXAMPLES: a = bindgen(5) bitlis,a,b print,b 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 1 1 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 *SYSTEM VARIABLES USED: none *INTERACTIVE INPUT: none *SUBROUTINES CALLED: none *FILES USED: none *SIDE EFFECTS: *RESTRICTIONS: Input parameter must be scalar or vector and either byte, integer or longword integer data type. *NOTES: When integers are stored in two's complement, the bit pattern for negative numbers will be different than for positive numbers. *PROCEDURE: Each bit in the input parameter is checked. Note that negative integers are stored in twos complement form. Therefore, the left-most bits are ON rather than OFF as they are for positive numbers. Input the absolute value of A is negative numbers to avoid this problem. If the input parameter is a integer vector with N elements, the output parameter will be an array with 16xN elements, with the first bit status contained in the first column 0, second bit in the second column, etc. A scalar byte value would produce a 8 element vector. Note when the output parameter is displayed, the bit order will be opposite that normally used for displaying bit patterns (i.e., the least significant bit is on the left and the most significant is on the right). *MODIFICATION HISTORY: 3/30/93 rwt allow byte data Dec 1998 removed use of PARCHECK; incorporated BITTEST code
