Question:

Is it possible to use ItemLocate to find the position of a particular character in a string, and then select the two characters to the left of the located character?

Answer:

Umm. No. This would require use of the string functions. Something like:

        DaString="ABCQXYZ"
        DaChar="Q"
        a=StrIndex(DaString,DaChar,0,@FWDSCAN)
        DaAnswer=StrSub(DaString,a-2,2)

More examples:

I'm interested in is some string manipulation tools, such as StrRight, StrLeft, StrMid, i.e be able to ask for the left 5 char's from a string, or from the right, or even say for the 6 chars 3rd from the left.

Here's an example using the StrSub function:

1. Left 5 chars:
   

   newstring=strsub(oldstring,1,5) 
   

2. Right 5 chars:
   

   newstring=strsub(oldstring, strlen(oldstring)-5,5) 
   

3. 6 chars 3rd from left:

   newstring=strsub(oldstring,3,6)
