Cuveesoft.ch emulators - getting programs to them on an iPhone

[RobertM]

So when I try (for example) Don Shepard's Prime Factor program, pasting the program in shows three errors:

X<-->Y should be X<>Y
X=/=Y should be X#Y (this occurs twice in the program).

If you change those in your source text, then pasting it in and running it seems to work for me.

Edit: you can find a list of accepted mnemonics here.
