Question about Scope of Variables

[blaze077]

Can a run-time filter change the value defined for a variable in the top-level script?

The following code does not change the value of x from 5 to 6.

BlankClip(length=240, width=640, height=480, pixel_type="RGB32", fps=24, fps_denominator=1, audio_rate=44100, channels=1, sample_type="16bit", color=$000000)
x = 5
FrameEvaluate("x = 6", show=false, after_frame=false)
Subtitle(String(x))

And can a run-time function pass a global variable?

The following code does not define a value for x.

BlankClip(length=240, width=640, height=480, pixel_type="RGB32", fps=24, fps_denominator=1, audio_rate=44100, channels=1, sample_type="16bit", color=$000000)
FrameEvaluate("global x = current_frame")
Subtitle(String(x))

Thank you.
