OR (Inclusive
OR)
MB = MB | MB;
MB = MB | 1;
MW = MW | MW;
MW = MW | 00FFH;
ML = ML | ML;
ML = ML | 00FF00FFH;
MQ = MQ | MQ;
MQ = MQ | 00FF00FF 00FF00FFH;
Performs a bit or integer inclu-
sive OR operation.
& AND (AND)
MB = MB & MB;
MB = MB & 1;
MW = MW & MW;
MW = MW & 00FFH;
ML = ML & ML;
ML = ML & 00F
F00FFH;
MQ = MQ & MQ;
MQ =
MQ & 00FF00FF 00FF00FFH;
Performs a bit or integer AND
operation.
^
XOR (Exclu-
sive OR)
MW = MW ^ MW;
MW = MW ^ 00FFH;
ML = ML ^ ML;
ML = ML ^ 00FF00FFH;
MQ = MQ ^ MQ;
MQ = MWQ ^ 00FF00FF
00FF00FFH;
Performs an integer exclusive
OR operation.

Used in an IF or WHILE condi-
tional expression. If the left side
and right side are the same,
the condition is TRUE.

IF MF < > MF;
WHILE MF < > MF;
IF MQ < > MQ;
WHILE MQ <

IF MD < > MD;
WHILE MD < > MD;
Used in an IF or WHILE condi-
tional expression. If the left side
and the right side do not
match, the condition is TRUE.
