Finds the least-significant bit.
int FindLSB( uint32 mask )
FindLSB() finds the lowest-numbered bit that is set in the argument. The least-significant bit is bit number 1, and the most-significant bit is bit 32.
FindLSB() returns the number of the lowest-numbered bit that is set in the argument (for example, 1 if the value of the argument is 1 or 3 or 7, 3 if the value of the argument is 4 or 12). If no bits are set, the procedure returns 0.
Convenience call implemented in clib.lib V20.
