I have an example of bleed between iterations of [Test].
Code:
var *r = NULL;
function main() {
if (!r) {
r = malloc(sizeof(var));
*r = random();
printf("\nAssigning r=%f", *r);
}
printf("\nr=%f", *r);
}
Press [Test] twice. Output:
Code:
Zorro 1.16.4 Trading Automaton
Made with Gamestudio by oP group 2013
float compiling.............. ok
Assigning r=0.394250
r=0.394250
float run.. ok
r=0.394250
Observed: global var *r is not reset to NULL upon re-run of script. Expected: Iterations to be independent.

Yes, this is quite an unexpected behaviour, and we all had to learn it the hard way. But, it's a documented behaviour. You MUST initialize variables in the INITRUN phase!
Global and static variables are used in many programming languages, and they always keep their values until the program exits.
In the case of Zorro, there is no main() function and a script is only exited when it's modified or a new script is selected. Clicking [Test] or [Result] do not exit the script. There are several good reasons for this, but it is indeed unexpected, especially when you're used to 'normal' programs that exit at the end of the main() function.
