Description

Performs a bitwise mask set operation.

Returns

A number, bitwise masked with length bits of mask beginning at start.

Function syntax

BitMaskSet(number, mask, start, length)

Parameters

Parameter	Description
number	32-bit signed integer
mask	32-bit signed integer; mask
start	Integer, in the range 0-31, inclusive; start bit for mask
length	Integer, in the range 0-31, inclusive; length of mask
