BCC is an alternative ACS compiler.
BCC fails to mark named clientside scripts as clientside, so they end up actually being serverside. Instead, it marks an unnamed script as clientside.
function int f() {} // returns 0
If a function that returns a value reaches the end, and there is no “return” statement at the end, the function returns 0. This is done to avoid false compiler errors like this:
function int f(void) { if (x) return 1; else return 2; // ACC will complain that the function doesn't return a value }
