Thanks, that works in ksh also.
I forgot to say that I need a solution
that uses sh only. Sorry.
I got an additional hint and solved the problem using expr:
LEN=`expr length $VAR` # store length of $VAR in
$LEN
LEN=`expr $LEN - 1` # decrement $LEN by 1
VAR=`expr substr $VAR 1 $LEN` # change $VAR to substring of
$VAR
