GetInt8 - method of the PmBuffer object

Reading the integer 1 byte value.

Long GetInt8(Long nOffset)

Value = PmBuffer.GetInt8(nOffset)

nOffset	(Long) Defines the position of read value in the data block. The read value must be inside the data block. The item is read either whole or not read at all. >= 0 - Index (in bytes, zero-based index) in data block. -4 - The internal automatic position is used (see AutoOffset). It points behind the last read or written value and increases continually. If the items are read/written one by one then it is not necessary to define the position, but it is handy to use this automated positioning.
