XGP status

[larsbrinkhoff]

(This is just an informative note.) The Name Dragon includes the status of the XGP printer if there is a XGP XGPSPL job. It reads three words from location 75 in that job, then one word from 70.

Looking into the XGPSPL source code, we can find this:

loc 70

;  NOTE!!  Do not, repeat, NOT mung these locations without changing
; XGPDEV too.  XGPDEV depends upon locations 70-101 being these parameters
; and in this order(when it reads USR:XGP XGPSPL).
