Read http://www.amibroker.com/guide/a_userfunctions.html
Then try changing your function signature to just take a parameter
and move the declaration out of the if statement.
e.g.
function P1f(sys) {
if (sys == 1) {
...
}
...
}
Alternatively, you could create different functions for each scenario
and check a condition in your calling code to determine which one to
call.
e.g.
...
if (sys == 1) {
P1f();
} else {
OtherP1f();
}
...
function P1f() {
...
}
function OtherP1f() {
...
}
I don't understand your scope question. But you may find the
documentation for local/global helpful:
