You could use PHP or Python inside bash scripts.
php -f script.php

You can use php's interbase module, or kinderbasdb for Python to "talk"
to database.

Unfortunatelly, isql always return the same value. You can try my tool
FBExport that returns 0 on success, and negative numbers on error.
However, it can only execute inline scripts, so you would have to create
the entire lines by yourself, for example:

fbexport -X -D/path/to/db -Q "EXECUTE PROCEDURE xyz..."

What you need does not exists, but you can add feature request for isql,
since it would be a really useful feature.

I'm even considering to add this feature to fbexport... until then, I
still suggest you to use PHP or Python or even C++ (via IBPP) for this.
