Simple Q -- count variable in loop

I need to do something very simple, and as I'm a newbie, I need some help. How do I get a count of items processed in a loop? Using ksh.

A simple example:

for file in `ls ${stagedir}/*.txt`

do
mv ${file} ${workdir}
# count variable here -- x++

done

echo "${x} files were moved"

Thanks!

Never mind. Got it. Sorry for the super-simple question!

count=0
for file in `ls ${stagedir}/*.txt`

do
mv ${file} ${workdir}
count=`expr $count + 1`

done

echo "$count files were moved"

Thanks,
Stacy
