Can someone please explain the significance of that to me? Is it
different from a function?
Functionally (all puns intended), "command" is synonymous with "on".
"Command" was added to distinguish between message handlers and
commands, though that distinction is stylistic; AFAIK they can be
usdd interchangeably.
Thanks... I was wondering if I was missing out on some new script
goodies there. ;-)
Possibly one: have you started using the new "private" keyword?
E.g.:
private function EmpName
return fld "FirstName" && fld "LastName"
end EmpName
By specifying a command or function as "private" means it can only be
accessed by other handers in the same script.
This has two benefits:
1. It helps keep some handlers from being called, things like internal
utility functions in a library stack.
2. Speed: being available only to the local handler, they trim a fair
bit of the message-passing overhead. While the time to call both a
private and public handler is too small to be noticeable in a single
call, access time to private handlers benchmark about 30% faster, so for
frequently-accessed handlers it can be useful.
