Don't create it as a part of WHEN-VALIDATE-ITEM trigger - create it as a function (you'll see a node in Object Navigator window). Doing so, you can call it from wherever you want.

That'd allow you to call it from anywhere within the form. To call it from other forms it'd need to go in a pll or the database.

Right; what I meant (and never said) was that it is any trigger or a procedure within that form. Today it is "normal" to put such a code (that is used more than once) into its own, well, "program unit". However, if someone insists, it is possible to leave it in a trigger and call it with EXECUTE_TRIGGER.

I can't test it now, but I *suppose* it is still here (for backward compatibility, I'd say) as the "old" Forms versions (prior to 3.0) didn't have "Program units" section so EXECUTE_TRIGGER was the only way to do such a job (i.e. reuse piece of code).
