Is it possible for a script to determine whether a given string, containing no
carriage returns, can be placed in a particular field (window) and have each 
char. of the string be immediately visible?  

The problem is that i have fields that have a fixed width, but can vary in
height, and i don't want them to be any taller than necessary to reveal
the entire string that they hold.  So, i need a way to figure out how many
"lines" of the particular field are necessary to encompass the entire string.
NOTE:  by "line" i don't mean the HyperTalk conception of strings separated by
carriage returns, but instead a horizontal slice of the particular field 
having height equal to the height in pixels of the particular font/size comb-
ination of text.

I'm fairly sure that HyperTalk offers no solution or work-around.  I know
almost nothing about XCMDs and XFCNs.  
I would appreciate any advice on the problem.
Thank You,
