on the html view(http://decompiler.theautomaters.com/pco ... es.php?t=1)
i added links to get to the corralating post on phpBB....that will make it so that you dont have to search though the 31 pages for a specific opcode...
default on html view is column headers on....
default on text view is column headers off....

Ok, now explain what the blazes all that shorthand is!
I look at an easy one, like opcode 1C, which is BranchF. Now, I know that this means Branch if the stack is FFFFFFFF and where to branch to, etc. But how do I decode ">p" and "If (%p1) Then||End If". It would seem intuitive that the source code equivalent should be "if ?? = false then goto <someplace>.....endif". So, does "%" mean "not", as in "if not ??...", etc. Also, should the comments column explain how it works? That is, should a text explanation of the opcode go there, or are we really just more concerned with what we need to know to translate it into source code,and thus put "if ?? = false then goto <someplace>......endif" there?

lol sorry it will all be explained in due time......first of all the %pX is a reference to something off the stack...
search the string for the highest X value for example in opcode(2A) is the concat str
it has no args....therefore no argstr.....
the srcstr is "<%p2 & %p1"
the highest %pX is %p2....so take 2 items off the stack....and insert them in place of the %pX
the leading "<" tells us to push the result back to the stack
ill explain the ArgStr next.....

Ah, this sounds suspiciously like the way VB3 works; does it remind anyone of RPN?
Ok, thanks..I'll try to convert my thinking!
