@Quigbo -- Perhaps you could use the 'OpenLib' and 'ExecLib' as tokens?

@Everybody else -- I've heard of the 'continue' from my brief forays into Python, but I'm not entirely certain what that could be used for.  Explanation please?

Continue skips the rest of the loop and starts another iteration.

For the goto-if and goto-!if I think I will auto-optimize the existing commands instead of creating entirely new syntax.  It would actually be easier I think to read and write and no one would have to change their syntax.  Same thing with sub().

Lol way back when Axe was a baby ^^ And those auto optimizations sound actually pretty neat

Return already has a ReturnIf and Return!If version.  But I guess I could still optimize it anyway in case someone forgets.

Speaking of optimizing control structures, any chance for Do...While loops?

I'd like Switch cases more than Do...While loops, but I don't really know how the second works.

Do...While loops are a lot like While...End loops, except that the check to advance to another iteration of the loop is at the end instead of the beginning. This turns out to be more optimized. Whereas a While...End loop has two jumps, one to exit the loop if the condition is false and one to jump back to the beginning, a Do...While combines the two into one jump that jumps back to the beginning if the condition is true.

I don't know how good that explanation was, but perhaps this pseudocode will help clarify it. Numbers in brackets indicate the number of bytes the real code takes:

While...End loop		Do...While loop
Code: [Select] ;While [x] Loop condition [2] Check if loop condition is true or false [3] Exit the loop if false ;Loop contents ;End [3] Jump back to the beginning of the loop		Code: [Select] ;Do ;[0] Start of the loop, takes no actual code ;Loop contents ;While [x] Loop condition [2] Check if loop condition is true or false [3] Jump back to the beginning of the loop if true

@Runner, I was thinking of having "While 1" and "Repeat 0" to auto optimize to no code at all so that would take care of the Do part.  The end condition might work if I add new "EndIf" and "End!If" instructions (which only work on while/repeat loops).  It would be pretty cool too because it would mean you can have pre-check and post-check for the same loop!  Something I haven't seen yet in other languages...

@Builderboy: Very difficult.  The new algorithm has no knowledge of X and Y while drawing the line so it doesn't know when its going off-screen.  If I let it keep drawing, it continues writing to more of the screen ram causing a loop around effect and a possible crash if it goes too far off screen past the end of the L6 buffer.  Likely the next version will just draw nothing if you go off-screen as that would give a size and speed optimization and is more likely what you would want in that case.
