function to calculate string length...

[Frank Leahy]

If you have strings that are much longer than the field size, then 
using a binary algorithm might be faster.  Check the string length, if 
too big, then check the length of 1/2 the string, if too small, then 
check the length of 3/4 of the string, and so on until you get within a 
character or two.  You could also take the width of a medium character, 
such as "n", and use that to get you to within a couple of chars of the 
correct length.
