AutoOffset - property of the PmBuffer object

The internal automated positioning in the data block works automatically (but can also be set by script).
Long AutoOffset
s = oBuffer.AutoOffset
Property access for read and write.

After each successfull read/write operation of a value in the data block, this property is automatically set to the end (behind) yhe read/written value (to the beginning of next read/written value). This can be used for continuous value reading/writing or for detecting the number of read/written bytes by the difference of the value of this property before the operation and after the operation.

The read/write position is available in the form of the nOffset parameter in each method working with the item or a portion of the data block, where the value -4 means that the value of this internal positioning AutoOffset is used.
