I investigate this problem: you have to set the $009A to $00 (program mode,
system errors not printed), and you call the i/o functions, as usual,
but when returns a function, and the carry is set, there's an error occured, the error code is in Accu.
error codes:
01: too many files
02: file open
03: file not open
04: file not exists
05: device not present
06: not an input file
07: not an output file
08: missing file name
09: illegal device number
(the handler routine is in rom from $f273)
bye,
gega
