Dear all,
I don't know if here is the right place to ask or not.

Do someone ever use command ONE? Is a command that launch a task if one error occured but on the documentation there is no example.
Do someone has an example?

Thanks in advance

I didn't ever used "ONE", but I guess you have to place the command in one of the first lines of your PROGRAM to tell the controller what to if an error occured:

.PROGRAM Main ()
    ;
    ;
    ONE PrintErr
    ;
    ; other commands here
    :
.END
 

.PROGRAM PrintErr ()
    PRINT "Error!"
    RETURNE
.END
 
 

Thanks,
I already tried to do this, but the controller seemes ignore the command...

I don't think the control unit simply ignores it. My colleague sent me a little test program that does exactly what you expect. These are the inputs and outputs of the terminal:
