Unable to properly execute a let statement from a shell script

- Subject: Unable to properly execute a let statement from a shell script
Hi all,
I am running bash on XP
I have a very simple script a.sh
a.sh:
====================
export P=1
let Q=$P+1
echo P=$P
echo Q=$Q
====================
Case 1)
If at prompt I run:
a.sh
let: not found
P=1
Q=
Case 2)
If I run:
bash a.sh
P=1
Q=2
I know that I could modify a.sh by adding #!/bin/bash
at the top of the file but I would need to avoid this
otherwise I have to modify too many scripts
Is there a way to run a.sh like in Case 1 and get the
proper result like in Case 2?
Thanks
Paolo
