Oops, a few corrections, re-upped zip (only had 1 download, no version bump).

Post #2 correction (Final was originally another name, and default True, forgot to invert some True's to False and False to True)

Final Default False,       If False, then DOES NOT Delete any ranges, replace only. Delete Operations only occur if this arg is True.
                             Set False, when using SawBones together with NotePad and VirtualDubFilterMod (with Script Editor Window Open).
                             When False, will not do deletions, will instead show frames marked with "DUMMY DELETE" in frame center.
                             Purpose, to avoid editing errors using SawBones v1.04 "Save & Refresh" AVS, keyboard command. (Not a
                             good idea to edit clip where deletions have already been done, ie edits after first deletion, would all be wrong).
                             Change to FINAL=True, when all edits including deletions are complete, where real deletions will ensue.
                             If later adding some edits to a command file using SawBones, then set FINAL=False until editing complete.

Post #3 correction (was "SplitCommands: ")

myName="FrameSurgeonSplitCommands: "

Post #4 correction (somehow got changed back to $KEY_CTRL_SHIFT_ALT & "?", would still work same (at least on my keyboard)

Global $USER_KEY_InterpRange=$KEY_CTRL_SHIFT_ALT & "/"  ; User can choose a suitable key for Interpolate Range (default "?")
# EDIT: Above, Damn, should be changed in comment too

Posts 2, 3 and 4 corrected.

EDIT: In re-upped zip, also made this amendment to FrameSurgeon_DEMO.avs (show STACK 6 windows, with FX1->FX4, was only FX1->FX2)

Import("../FrameSurgeon.avs")

EDIT: DAMN, default in FrameSurgeon for Final should be false, but its true. (EDIT: Or should stay true, hard to decide)
