Some programs and transient utilities optionally display
their version string on startup. Many do this by reading
the ANFS 'Display Version' configuration setting set with
*-Net-Opt8,2 or *-Net-Opt8,3.
This can easily be done with the following code:
LDA #&A1 :\ A=&A1 to read Config settings LDX #&11 :\ Location 17 is ANFS settings LDY #&00 :\ Preload Y with &00 if no response JSR OSBYTE :\ Read Config setting TYA :\ Set N flag from returned setting BPL NoMessage :\ If b7=0, don't print message \ Print message .NoMessage
Similarly in BASIC:
IF FNbyte(161,17,0)AND&80:PRINT version$
