Re: Another ProDOS ?

It is pretty-well impossible to find a program which doesn't make ROM calls.
At least, to find a program that does something _useful_ without ROM calls
:-). But almost all are compatible between ProDOS and Dos 3.3. If however
your program is accessing the disk then you need a lot more changes than the
filename issue (unless it's an Applesoft program).
