Added a semicolon to the comment "If we ; need cursor ..." so it isn't seen as an undefined symbol ; edit 5, 20 July by OBSchou. Put in the cursor positioning code for ; all the terminal supported, and moved the vtval EQUs and defesc EQUs ; here if the system requires andn external terminal. If the system ; has a 'built in' terminal (ie own scrteen driver) you will not come ; to this file, so you must declare these three lables etc in your ; own code. ; This will allow only those systems requiring a terminal to require ; CPXVDU.ASM during assembly. ; ; edit 4, 16 July, 1987 by OBSchou for will Rose. ; Added code for Ampro 230 terminal ; ; edit 3, 15 July, 1987 by OBSchou for David Moore.
