Help to find length of string avoiding trailing spaces

Hi,
I have a record of length 200 bytes and values filled is only 100 bytes and remaining 100 spaces is occupied by spaces. In script wen i try to find the length of the entire record it should get as 200 not 100. i tried using length and wc -c but it doesnt work can anyone have any idea on this???
Tis was the code i tried:-
Code:
cat RPCSFILE.txt | grep '^D' | while read LINE
do
expr length '$LINE' | read LEN
if [$LEN -ne 200]; then 
echo "Incorrect line"
fi
done

NAME
script - make record of a terminal session SYNOPSIS
script [-a] [filename] DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the record is saved in the file typescript. See WARNINGS. The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends when the forked shell exits or when Control-d is typed. OPTIONS
The following option is supported: -a Appends the session record to filename, rather than overwriting it. NOTES
script places everything that appears on the screen in filename, including prompts. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |CSI |Enabled | +-----------------------------+-----------------------------+ SEE ALSO
attributes(5) WARNINGS
script can pose a security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a privileged user, that is, root. Be sure that typescript is not a link before running script. SunOS 5.10 30 Jan 2004 script(1)
