Definition Constructs Can Include Global Variable Declarations At Top Level

Definition Constructs Can Include Global Variable Declarations At Top Level

All the major definition constructs in MAXScript (such as, utility, rollout, macroScript, rcmenu, tool, plug-in, and others) can now include global variable declarations at the top-level within them.

rollout foo "foo"
(
local a, b = undefined, c
global d, f = 3 -- now possible
spinner bar "Bar"
checkBox baz "Baz: "
on bar changed do print a --etc
)

In releases prior to 3ds Max 4, globals had to be declared inside on-handler bodies. Any initializers present in a global declaration like this are at compile time, so the initial value expressions must be executable at the time the script is compiled.
