SetBit - method of the PmBuffer object

Description:

Writing a single bit.

Syntax:

Empty SetBit(Long nOffset, Long nBitIndex, Boolean bValue)

Parameters:

nOffset	(Long) Specifies the position of written value in the data block. The whole written value must be inside the data block, or the whole item is added to the end of the data block. The item is written either whole or not read at all. >= 0 - Index (in bytes, zero-based index) in the data block. -4 - The internal automatic position is used (see the AutoOffset property). It points behind the last read or written value. This operation does not shift the internal automatic position.
nBitIndex	(Long) Bit index (zero-based index). The value must be any non-negative integer If the value is greater than 7, then the value is internally divided by 8 (one byte size). The position (nOffset) is incremented by the integer part of the division and the bit is the remainder after integer division. The resulting bit position must be in an existing data region.
bValue	(Boolean) Written value.

Note:

This method is also functional in Web panels.

For this method, it cannot be set nOffset = -2 (contrary to methods SetUint8 …).

var oBuf = Pm.CreatePmBuffer();

oBuf.SetInt8(-2, 0);

oBuf.SetBit(0, 0, true);

oBuf.SetBit(0, 1, true);

oBuf.SetBit(0, 2, false);

oBuf.SetBit(0, 3, true);
