Garret, do you mean something like this?

   line 10 to 20 of fld "myfld"

Or do you need to select from a specific character of a specific line  
to a specific character on another line? The following, for instance,  
is not legal syntax:

   char 5 of line 10 to char 1 of line 20 of fld "myfld" ---no workee

(as you've probably figured out.)

I would try something like:

put length(line 1 to 9 of fld "myfld" into startchr
put length(line 1 to 19 of fld "myfld" into endchr
select char startchr to endchr of fld "myfld"
--(or whatever you want to do with the chunk

Is this what you're after?
