Manipulating a variable across multiple shell scripts
I have a shell script similar to:

#!/bin/sh
a=1
source a1.sh -- Modifies a
source a2.sh -- Modifies a
echo "After execution, value of a is $a"

What i need is a1.sh script modify the same variable a and same with a2.sh. Now the echo "After execution, value of a is $a" should print the value of a after manipulation in the scripts, and not 1 (value in calling script).
Is it possible?
