The "CONTINUE" command after a "Contol-C" in the chat window is a very useful command for debugging programs.
Unfortunately, it is only very limited to use.
Up to version V5.2, the "CONTINUE" command still worked correctly after a "Contol-C".
The following small program demonstrates the problem that only starts with version V5.3.
Unfortunately, "continue" does not work correctly even with the newer MM, MM + and MZ versions.
The error only occurs after inserting the subroutine.
------------------------------
THE TEST PROGRAM

DO
PAUSE 500
PRINT "HELLO WORLD"
TEST()
LOOP

SUB TEST ()
FOR i = 1 TO 30
PAUSE 50
NEXT i
END SUB

------------------------------
RESULT

RUN
HELLO WORLD
HELLO WORLD
'CONTOL-C pressed = program stop
> continue
[5] Loop
Error: LOOP without a matching DO

This is a known issue. The problem occurs when the crtl-c happens when execution is in the subroutine. Geoff is aware.

Yes, unfortunately as MMBasic has become more sophisticated (subroutines, CFunctions, etc), resuming after a CTRL-C has become more difficult. I have it on my list to fix but the answer might be to remove the CONTINUE command or at least restrict its use (not good).

By the way, greetings to Austria. I was there just a week ago (St P�lten and Vienna) and I loved your wines, particularly Sturm which was completely new to me.

Geoff, you should have tried this "Schilcher Sturm"
In my opinion it has much more flavour than the usual types

It is made of a special grape (Blauer Wildbacher) which only grows in a small region in southern Austria

For the NonAustrians:
Sturm is grapejuice which started fermenting and then gets cooled to stop the process, before becoming wine
So it has some alcohol already and a "bubbly" taste

Its a pity I did not know that you were around
I live close to Vienna and would have loved to show you the area

cheers
Guenter
