[Swftools-common] Unknown Tag 777 length 3

[Ian Ilsley]

The following script :

.flash filename="test.swf" bbox=200x200 fps=12 version=7 background=#000000
.frame 1
.action:
title="Hello World";
.end
.end

compiles fine - but when I dump out the swf with flasm I get an Unknown 
tag 777

movie 'test.swf' // flash 7, total frames: 1, frame rate: 12 fps, 200x200 px
 // unknown tag 777 length 3
 frame 0
   constants 'title', 'Hello World'
   push 'title', 'Hello World'
   setVariable
 end // of frame 0
end

also if I dump it out with swfdump there is some 'extra byte' on the 
FRAMELABEL .

[HEADER]        File version: 7
[HEADER]        File size: 72
[HEADER]        Frame rate: 12.000000
[HEADER]        Frame count: 1
[HEADER]        Movie width: 200.00
[HEADER]        Movie height: 200.00
