GetInt8 - method of object PmBuffer

Description:
Reading the integer 1 byte value.
Syntax:
Long GetInt8(Long nOffset)
Calling:
Value = PmBuffer.GetInt8(nOffset)
Parameters:
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.

Note:
This method is also functional in Web panels.
