return DB2 SQLCODE

Hello All,

I have 2 shell scripts.
script1.sh
script2.sh

script1.sh call script2.sh

script2 will connect to DB2 database and execute a insert statement. I am capturing the return value of insert statement in an variable called SQLCODE. I want to return this SQLCODE to the calling script script1.sh

SQLCODE can have negative values and positive values which are more than 255. There should be a way to send the SQLCODE accross the scripts. How do I return or capture the SQLCODE in script1?

exit $SQLCODE or exit $RETCODE does not help.

Thanks for the help. Appreciate it.
