Purpose
Function to test the value of a specified bit in a numeric value
Syntax
BITTEST(<expN1>,<expN2>)
See Also
BITAND(), BITCLEAR(), BITLSHIFT(), BITNOT(), BITOR(), BITRSHIFT(), BITSET(), BITXOR()
Description
The BITTEST() function tests the value of the specified bit <expN2> in a numeric value <expN1>. If the bit is 1, BITTEST() returns True (.T.), otherwise it returns False (.F.). If <expN1> and <expN2> are not integers, they will be converted to integer values before the clear takes place. The bit position, <expN2>, can range from 0 (rightmost bit) to 31.
Example
x = 6 && 0110 y = 3 z = 2 ? bittest (x,y) .F. ? bittest (x,z) .T.
