AND

The AND instruction provides bit manipulation by logically ANDing the source with the destination and storing the result over the destination. It uses one of the following formats:

(1)	[label]	AND	{source1}{sep}{dest1}
(2)	[label]	AND	{source2}{sep}{dest2}

Where:

label

Optional. A Program Execution Label.

source1

Required. A previously defined Character String Variable single character Literal decimal constant, or equivalent {ctrl} character that is ANDed with the {dest} operand.

sep

Required. A comma or one of the following prepositions: BY, TO, OF, FROM, USING, WITH, IN, or INTO.

dest1

Required. A previously defined Character String Variable that is ANDed with the {source} operand contains the results.

source2

Required. A previously defined INTEGER variable that is ANDed with the {dest} operand.

dest2

Required. A previously defined INTEGER that is ANDed with the {source} operand contains the results.

Flags Affected: EOS, ZERO

Note the following:

The {source} operand remains unchanged.
If the {source} or {dest} is a Null String, the EOS Condition Flag is set.
If the result is zero, the ZERO Condition Flag is set.
Any bit in the character may be manipulated.
Enhanced ARRAY processing is supported for the AND instruction.
The following truth table indicates the results of the operation on each bit:

Source	Dest	Result
0	0	0
0	1	0
1	0	0
1	1	1

Example 1:

AND

SENDING TO RECVING

	Variable	PL	FP	LP	Contents
Before:	SENDING	6	3	6	ABCDEF
	RECVING	8	1	8	N2345678

After:	SENDING	6	3	6	ABCDEF
	RECVING	8	1	8	B2345678

No Condition Flags are set (all FALSE).

'C' ==> 0100 0011

'N' ==> 0100 1110

--------------------

'B' ==> 0100 0010

Example 2:

AND

HEX_FFF0 COUNTER

	Variable	PL	FP	LP	Contents
Before:	HEX_FFF0	2			0x11111111 11110000
	COUNTER	2			0x0 01110111
After:	COUNTER	2			0x0 01110000

No Condition Flags are set (all FALSE).

0xFFF0 ==> 1111 1111 1111 0000

119 ==> 0000 0000 0111 0111

-------------------------------

116 ==> 0000 0000 0111 0000
