TCL Globals

[conzar]

I'm having trouble using global variables in tcl.

Here is an example of my problem

proc test {}{
    global PI
    set PI 3.14
    test2
}

proc test2 {}{
    puts $PI
}

Whats wrong with this? Or does AC3D use an interpreter that doesn't allow globals?

ok, figured out what I'm doing wrong.

Change the code to the following and it works.

proc test {}{
    global PI
    set PI 3.14
    test2
}

proc test2 {}{
    global PI
    puts $PI
}
