CBL_AND

The CBL_AND library routine compares each bit of the first operand to the corresponding bit of the second operand. If both bits are 1, the corresponding result bit is set to 1. Otherwise, the corresponding result bit is set to 0.

Source	Target	Result
0	0	0
0	1	0
1	0	0
1	1	1

Syntax:

CALL "CBL_AND" USING source                        destination                       [length]                GIVING returnCode

Parameters:

source	PIC X(n)	Specifies the first operand.
destination	PIC X(n)	Specifies the second operand and receives the result of the operation.
length	any numeric data item or numeric literal	Specifies the number of bytes to be considered when executing the routine. When this parameter is omitted, all bytes in source are used.

Return code:

returnCode can be any numeric data item and provides additional information:

0	Operation successful.
1	Operation failed.

Examples:

Example - Get the bit level AND result between characters 3 and 4
