: '''FUNCTION''': Reports the current horizontal POSition of the text cursor relative to the left edge of the text window. The <stream expression> MUST be specified, and does NOT default to #0.
: POS(#8) reports the current horizontal carriage position for the printer, where 1 is the extreme left hand edge.
: POS(#9) reports the logical position in the disc file stream, i.e. the number of printing characters sent to the stream since the last carriage return.
