[comp.sys.atari.st] AMC-GDOS fonts to GDOS fonts

J.D.Coleman@newcastle.ac.uk (Julian Coleman) (09/26/90)

I am having problems with AMC-GDOS in that some Gem programs cause the error :
                ---------------------------------------
                |  /--\                               |
                | |STOP|  GDOS-Error : invalid handle |
                |  \--/                               |
                |              --------               |
                |              | QUIT |               |
                |              --------               |
                ---------------------------------------
Having written a program to look into this, it occurs when opening or closing
a virtual screen workstation.  This error only occurs with AMC-GDOS and not
Atari GDOS.
Any ideas, anyone?
The versions of GDOS I have are :

  AMC-GDOS Release 3.20 CRX ( UK )   { Came with Gemini1.1 - neat program :-) }
  Atari GDOS release 1.1             { Came with Opus2.2 spreadsheet }

A solution ( sort of ) would be to use Gemini with Atari GDOS but ...
   ... How do I convert the Gemini fonts to work with Atari GDOS?

Thanks in advance for any info,

                                  Julian

GDOS is faulty here, not AMC-GDOS. If you open/close a virtual workstation
with an invalid VDI handle AMC-GDOS notices this error and shows the alert
box above. GDOS simply ignores the error.
