Command Execute hook
Use this hook to perform the real actions for the custom form command. This hook can use actual values of the form fields.
Example:
function extern function.publish.command.execute()
{
string l.mess(200) mb
|* Publish item
if not txdll0007.item.publish(tcibd001.item, l.mess)
message(l.mess)
choice.again()
endif
}
