Calling a script with the use of the "dot-space" notation causes the script to be sourced in the current environment, that is, all the variables contained in the script will be available for use outside (in the for loop).

You can obtain the same effect with the bash "source" command builtin (have a look at bash man page). According to that, the return status will be the status returned by the last executed command in the script, so your code should be ok.

Maybe you're not using bash, other shells could possibly behave differently (I don't know).

Anyway, I don't see the need for you to call the script in that way, simply modify your "execute_another_script.sh" script, let it read the $1 variable from the command line and pass directly the "filename" value to the script in the for loop:

Code:
for filename in AH1 AH2 AH3
do
   execute_another_script.sh $filename
   echo $?
done
