[71B] How to make a lex file

[caloubugs]

Hello,

I'm a newbie here but i own a 71b, 15c, 48g.
The fact is that i want to make a lex file in my 71b (using the forth ROM). A real one, not an emulator.

Just for testing the process, i used edtext to write the code (an exemple given by HP in the manual with the pseudo-ops wanted) and the ASSEMBLE word after in the forth mode.

But everytime i have the error message : "missing/multiple file type".

I dont see what is wrong.
And, can i find any "howto" to make this.

Tanks a lot for help !
