copy program from rom module in emu71

[hesc]

In the meantime I figured out by other forum mail that I can directly copy from, in this case, port(x). So with the command CAT :PORT(2) I was able to list the rom and e.g. with COPY KEYWAIT:PORT(2) TO :TAPE I could copy most files from ROM, included LEX files.
However, there was 1 file Circuit LEX which I could not copy. Is it protected in a way?

Best regards,

Henk
