This example will show the various way that are allowed in order to check if a specific (shift) bit is on or off. The first is by using the BIT
function, that check for a specific bit. The second is using the keywords BIT…OF
, that is a synonym of the previous function. Finally, we show the use of conditions HAS BIT
and IS
, that checks for specific bitmask.
CLS DO HOME PRINT SCANSHIFT left = BIT( SCANSHIFT, LEFT SHIFT ) PRINT "LEFT IS: ";left left = BIT LEFT SHIFT OF SCANSHIFT PRINT "LEFT IS: ";left IF SCANSHIFT HAS BIT LEFT SHIFT THEN : PRINT "LEFT" : ENDIF IF SCANSHIFT IS LEFT SHIFT THEN : PRINT "LEFT" : ENDIF IF SCANSHIFT HAS NOT BIT LEFT SHIFT THEN : PRINT "NOT LEFT" : ENDIF IF SCANSHIFT IS NOT LEFT SHIFT THEN : PRINT "NOT LEFT" : ENDIF LOOP
