IsBit()

Checks whether a bit at a specified position is set.

Syntax

IsBit( <nInteger>|<cHex>, [<nBitPos>]) --> lBitIsSet

Arguments

<nInteger>

A numeric 32-bit integer value can be specified as first parameter.

<cHex>

Alternatively, the integer can be passed as a hex-encoded character string (see NumToHex()).

<nBitPos>

The position of the bit to test is defined as a numeric value. <nBitPos> defaults to 1, and must be in the range between 1 and 32.

Return

The function returns .T. (true) when the bit at position <nBitPos> is set, otherwise .F. (false) is returned.
