Help me to write a loop counter

Hi,
I very need to write a loop ( containt while or until
or for ) that can count in ScoUnixOpenserver shell script (bash shell) .
I try to write a loop like follow but don't work correctly :

----------------------------------------------------------------
#!/bin/bash
clear
no=1
while test $no -le 100
do
no=expr $no + 1
echo $no
done
----------------------------------------------------------------
enyone can help me .
thank you for your note.
F.H.

See below for solution. Note the use of backquotes
to evaluate the expression.

Also the echo command needs to be before the count
increment - otherwise the numbers 2 to 101 are output.

no=1
while test $no -le 100
do
echo $no
no=`expr $no + 1`
done
