I'd be delighted to help but the source I have is in a box. It is from
Exploring ProDOS by Gary Little. Just TYPE filename with several other
parameters and that's it.

Nevertheless, I'm sure the TYPE extra command can be easily found on
asimov or any other FTP site but I have to admit I'm not good at such
researches. I personally still search for the SSAVE extra command!

I'm pretty sure a PROCMD disk contains such extra features.
