Pbasic 2.5 syntax
 

does anybody know where i can find a pbasic 2.5 language reference. I can't find it on the parallax website! help!

I don't think a full 2.5 code referance exsists. The only thing aviable is a PDF file included in the beta version that has the new syntax features. It should C:\Program Files\Parallax Inc\Stamp Editor v2.0 Beta 1\PBASIC Editor 2.0 Beta1.pdf. There is also a short cut in Start Menu->Programs->Parallax Inc->Stamp Editor 2.0 Beta 1->PBASIC Editor 2.0 Beta1.pdf.

Hope that helps.

<edit> Guess I was wrong. Oh well.</edit>

Does anybody know anything about the new scratchpad syntax. could somebody please explain it to me.

It's the same as the old stuff. If you aren't familiar with that, check out the Stamp manual from Parallax's website. You should look for the PUT and GET commands.

sorry this is my first time programming Pbasic. im mainly used to PHP and C++

Wasn't there supposed to be syntax highlight? I looked through everything, but nothing for highlighting. I also need a little bit of help. I shouldn't be asking this since I've done a comparision between the syntax, but how is switch used?

Parallax has said from the beginning that the alpha/beta versions won't have syntax highlighting but the final version will.

There is no "switch" command. There is a SELECT...CASE...ENDSELECT structure, which does the same thing. Ie:

SELECT counter
CASE 0 TO 100
'do stuff
CASE 101 TO 200
'do other stuff
CASE 201 TO 255
'do even more other stuff
CASE ELSE
'stuff to do if none of the previous cases match
ENDSELECT

There's other things you can put after CASE also (such as a single number or an operator and a number (ie >5)), but the above code is the basics.

D'oh...all well, sorry about that. I thought I mixed it up. Can you do "CASE > 4" or just "CASE pw_12 > 4"?

The first one is legal (CASE >4). The second is not legal syntax. Here's a good way to thing of the operators: imagine taking the SELECT variable/expression (from SELECT expr) and putting it immediately in front of the thing after CASE. ie
SELECT p1_y
CASE <127
...
can be thought of as an if with predicate p1_y<127.

So, SELECT / CASE is just like a easier IF/THEN statement in a way....nifty.
