Alright here is a super fast filled inverting recangle thingy.  It does use a fair number or variables though, if thats a problem you can always use memory locations instead.  So here is the code (its rather long)

Lbl RC
A^8->O
255->M
While O
M/2->M
O-1->O
End
C^8->O
255->N
While O
N/2->N
O-1->O
End
A/2/2/2->A
C/2/2/2->C
For(F,B,D-1
F*12+L6->J
{J+A} xor M->{J+A}
{J+C} xor N->{J+C}
For(G,A+1,C
{J+G} xor 255->{J+G}
End
End
Return

Its very fast, but if you want something smaller, you can use this:

Lbl RC
For(F,A,C-1
For(G,B,D-1
Pxl-Change(F,G
End
End
Return
For both, the input is A,B for top left corner and C,D for bottom right corner.

I use a professional version of Vegas to do all of my movies that i direct, and i like it a lot ^^

It will only be taken up when you turn interrupts on though right?  So those who dont use them wont have to give up or mem

Lol you could be tricky and be pg but put in a lot of innuendos so that all your pg audience will be unaware, and all your older audiences will get a kick out of it

Wewt, I have added basic editing to my program! Right now it only supports tokens that are found directly on the calculator keys, and without pressing 2nd or Alpha.  There is also no Deleting or clearing lines yet, although you can add data onto the end of a line making it bigger.  However, it will not resize the program, which means it cuts of data from the end of the program.  This is how it will have to work until i can get the memory management thing working

Here is a fun screenie showing the new features!

I am also starting work on implementing 2 byte tokens, which is proving to be a bit tricky.  As of now they just look appear as random symbols

Congrats on getting a demo out!  And a very shiny demo it is It has come so far, and is so awesome!  It really shows how far basic can be pushed.  And thats too bad about the data loss, but at least you had some good backups.  Cant wait to see this progress now that it is active again

And i will try to look at the movement code if i have some time, there might be a thing or two, but i doubt it, you have learned well young grasshopper

What i would do is make sure the variable is a valid input before the user inputs anything, so if they try a list, it wont change the variable and they will be just directed to the default screen for inputting weird data

Wow that looks terrific!  You've done a great job in 8x8 Its so small and yet so awesome!
