I've noted an inconsistent management of ' char to introduce a comment. For instance, in the program:
10 a=0 ' Zero
20 print "_"; ' Empty cell
The comment on line 10 is accepted, but the one on line 20 causes "Syntax error in 20"...
While on the parser topic, I wrote by mistake "while nor eof(1)" , and nor not being declared is 0, so the loop is skipped silently, while I would have preferred a "Syntax error".
Ok, I'm never happy, when I get a Syntax Error, I don't want it, and when I don't get one, I want it :-)
