# BIT FIND LAST CLEAR

Syntax

Bit Number = BIT FIND LAST CLEAR ( Source Bitset )

Description

This function will return the position of the last unset bit within the bitset. The function assumes that the bitset is a full 64 bits in size so checks should be made to ensure that the bit number returned is valid for the type that the bitset is stored in. If no unset bit is found, this function will return -1. You can store a bitset within variables of type byte, word, dword or double integer giving up to 64 bits.
