[amibroker] Re: How to convert a string to non-string characters?!

["ozzyapeman" <zoopfree@xxxxxxxxxxx>]

TJ, 

Thanks, quick question: 

I gave the arithmetic expression as a quick trivial example. But what
I really want to do is create and evaluate expressions of the type:

Condition1    = MA(C, 12) > C5  AND MA(C,20)    < Close; 

so for the above case, would you also recommend writing a
parser/interpreter - or did you suggest that purely for arithmetic
expressions like "1 + 2 + 3"?
