I have a variable with a value of "05". When I add one to that variable, using the command: CURR_YY=`expr $CURR_YY + 1`, I get the value of "6", losing the leading zero (which is needed for passing to another script). How do I keep the leading zero?

Thank you!

In KSH you can do this as follows:

typeset -R2 -Z CURR_YY=05
echo $CURR_YY

05

(( CURR_YY += 1 ))

echo $CURR_YY

06

#!/bin/ksh

typeset -Z2 a=6

echo "before->[${a}]"
((a=a+1))
echo "after->[${a}]"

Although we have korn shell here, the first line in our scripts set the environment to bourne shell (.#!/bin/sh), so the typeset command does not work. I apologize for not putting that in the initial posting. I'm still learning

#!/bin/sh

a='06'
echo "before->[${a}]"
a=`expr ${a} + 1|sed 's/^/0/'`
echo "after->[${a}]"

What happens in the year 2010?

I don't need to use the century in this code, so the code will work as I need it to.
