Help with string functions

[jellytot]

Hi all,

Can someone help me with the Expression Evaluator so I can do the following:

Say I have a Counter object. I also have an Active Object with the Alterable String A holding the string: "10, 20, 30".

Let's say I want to return the second element in the string (20) into the counter. How do I do that?

I don't have MMF in front of me so I don't remember the exact syntax of the commands but this is how I would do it.
Use the stringParser object. Set the delimiter to "," in the StringParser. Then set source string in stringparser to your AltStringA from your active. Then set your counter to listGetAt$( "String Parser", 2) <----It's in the list tokenizing section of the StringParser.

Alternatively, you could just use the String Tokenizer object.

Thanks guys!
I tried String Tokenizer, String Parser 2, and Tokens objects. String Parser 2 is great, but I'm going to use the Tokens object, since it allows me to retrieve an element in a string I specify, in a single expression.

Unfortunately, I can`t find an easy way to SET a tolken in a string, and then set that string back into the source object. Meh.


Anyway, thanks again!
