Following script outline (w/o TMF or other unsynchronized function calls):
Quote:
function run()
{
_POS(1);
...
...
... code comes here [with additional _POS(i) calls ...]
...
...
_POS(20); // Last _POS() call, just before run()'s exit
}

is generating the following error:
Quote:
Error 013: Invalid parameter ()
(20)

It seems like the error is somehow formed in the Zorro environment, not specifically associated with a function call. Can anybody advise: how such an error be troubleshooted/identified?

THX!
