AIR, often one needs to know if there is no occurrence of the substring, how does your instr function handle that?

Jade isn't BASIC.  ;D

Probably not but your casual and definitive "Jade is using a "0" based index" raised questions immediately from at least three BASIC-ers. Doesn't that ring the bell? ;D

If you try this, you will see that it returns a '-1'.

Code: C++
  1. include <jade.hpp>
  2.  
  3. MAIN
  4.     STRING blah("This is a string");
  5.     PRINT(INSTR(blah,"or"));
  6. END

AIR.

Sure looks like undef to me.

I encourage questions like this, but I also encourage you guys/gals to also try addressing your questions by coding.  I want you to find any issues; unfortunately I don't think zero vs one based indexing is one of them.  It's just different for BASIC-ers.  But not for people using other languages.

Armando, you telling this to me?! There's been nothing else but C/C++ for me to code in for decades! ;D

Never mind though. If there was at least one solid reason behind such a design decision for you as a (the?) project developer then so be it. :)

Code: [Select]
A$ = ""
IF MID(A$,69,3) = "AIR" THEN

TRUE in JADE returning -1.

 ;D ;D ;D ;D

TRUE = -1 is another BASIC oddity that's been making me dizzy for as long as I can remember.

But seriously, it's a good catch John!

Armando, the ball is on your side... ;)

Actually SB would return an undef for my example. Irritating but something I learned to live with.

John, you don't have to apologize. Armando will have to defend his design decision or admit his defeat.

Actually, this would throw an out of bounds error.

I updated MID$ to compare string length to start position.  Update and rebuild the lib.
