Subject: Advanced BASIC and Mouse support

Hi all,

I have Advanced BASIC working fine now, except that
the MOUSE support does not work. BASIC gives the error
'Missing Code' when I try to use commands such as
MOUSE ON, POINT TO, etc...

Jon Ripley has kindly scanned the page from the
Advanced BASIC manual regarding mice:
http://jonripley.com/volatile/7_Mouse_and_Pointer_Drivers.png

I have tried this with both the AMX Super ROM versions
3.31 and 3.41 and the Nidd Chauffeur ROM, and none of
these seem to work.

The manuals says that when AMX SuperROM is installed,
it pulls HIMEM down to &A400 and the Advanced BASIC
program to initialise AMX mouse support expects AMX
code to be around the &A400+ address location, as
shown by the following amxmice routine:

   10Mouse Driver For AMX SuperRom - PROCamxhelp for
DELETELOMEM
   20DEFPROCamxhelp:PRINT'"To use MOUSE in Advanced
BASIC with the AMX SuperRom:"''"1. SuperRom must be
present"'"2. enter Advanced BASIC"'"3. INSTALL the
file ""amxmice"""'"4. call PROCamxmice"':ENDPROC
  
30DEFPROCamxmice:TRACEOFF:IFLEFT$($&A404,29)<>"Mouse
Driver For AMX SuperRom"ERROR100,"Not INSTALLed
properly"ELSE LOCALERROR:ONERRORREPORT:PRINT":
SuperRom missing?":END
   40OSCLI"buttons off":OSCLI"pointer
on":OSCLI"sensitivity 1":CALL&A5A6:ENDPROC

However, I cannot find the text "Mouse Driver For AMX
SuperRom" anywhere within the AMX SuperROM image, and
there doesn't seem to be a routine &A5A6. However, AMX
SuperROM does work as commands such as *POINTER ON and
*ART work fine.

Does the AMX SuperROM not contain the actual Driver
that Advanced BASIC requires? Or am I doing something
else wrong? Does anyone have such a Driver?

Thanks,
Steve.
