Parameters

BinString
Type: Binary
Specifies a Varbinary or Blob expression.
StartBit
Type: Long
Specifies a starting zero-based number of the first bit to perform the operation as nStartBit and the number of bits to perform the operation as nBitCount.
If you do not specify nStartBit and nBitCount, the operation applies to all bits in the expression. If you specify nStartBit only, the operation applies to nStartBit only.

Return Value

Type: Binary
Numeric, Varbinary, or Blob. BitSet( ) returns the specified expression with the specified bit set to 1.
Examples
X#
1x = 5  // 0101 binary
2y = 1  // 2nd bit position (0 = 1st bit position)
3? BitSet(x,y) // Returns 7, 0111 binary
