FOR word$ IN string$ with empty word$ fails.

Hello.

I was under the presumption that if you declare a variable that you don't have to put an empty value in it anymore.
like:
  string$ = ""

And mostly this seems true.

You can declare a variable globaly, and then print it.
It prints nothing, but doesn't give an error.

You can test the variable if it is empty
  IF string$ = "" THEN
Without an error also.

But you can NOT

FOR this_word$ IN string$

PRINT this_word$

NEXT this_word$

It gives an 

ERROR: signal for SEGMENTATION FAULT received - memory invalid or array out of bounds? Try to compile the program with TRAP LOCAL to find the cause.

demo program:


GLOBAL string$

PRINT "string$ : " & string$

IF string$ = "" THEN PRINT "string$ = " & string$

FOR this_word$ IN string$
 
    PRINT this_word$
 
NEXT this_word$

Thanks Rik,

Actually, this is the same issue as you have mentioned before.

Declaring a string variable globally does not actually assign an empty string to that variable. It gets assigned a NULL, and that does not work for the delimited string engine.

The current 3.9.4 beta already contains a fix for this problem.

Best regards,
Peter

Aargh, I see now.

I thought I downloaded the newest fossil already, and actually I did.
But then I chose to have a 'new' OS again.

In my case this is only removing a data layer, for I'm working with Berryboot .
I realy thought that the new bacon was in the shared layer, and thus preserved.

This is what happens if your memory is not what it is supposed to be.

I can learn new languages, but I forget EVERYTHING after a few weeks.
That's why I like BaCon so much.
It's easyer to remember.

But even my own posts in the BaCon forum I forget so to see.
I'm realy sorry for this.

 Rik.
