#1587 how to edit import if there is no pcode for it
how would you edit thing such as "import MovieClip" if theres no pcode for it when clicking it on actionscript?
In AS3, imports are detected automatically from fully qualified names in P-code. There is no way to edit them standalone - just write P-code with these names and they will appear as imports.
