yes, the first one will use F1. the way it's set up is this. you choose an option from New, Open, Save, Quit. say you select Open. it will open a new menu to the right of the first one (like a computer does), and say 8x8, 16x16, 8x8 Set, 16x16 Set. once you select one, it will open a third and final menu which will contain Monochrome, 3Lvl Gray, 4Lvl Gray, and Masked. after you select that, it'll show all of the sprites with that type currently saved, and you can select one to edit.

hmm.. what calculator/OS?

German.

flexible-ish dropdown menu.
inputs - sub(MEN,Ypos*256+Xpos,numItems,"String1","String2","String3","String4") // String2-4 are optional. 0 < numItems < 5
String format:
cannot be more than 10 characters (bummer).
must be formatted like so: "4File". the 4 is the length of the string.
if you have a string greater than 9 in length, check this table to find out what you should put before the string. for example, ":Horizontal" will work.
outputs - integer 0-(numItems-1) indicating which option was selected

Lbl MEN
r1^256->X
r1/256->Y
0->Z
For(U,1,r2
Text(X+2,U-1*7+Y+1,{U*2+°r2}^r->V+1
!If Z:V->Z:End
If {V}>{Z}
V->Z:End
End
{Z}-48->{Z}
ZAsm(EFB44C6F2600)->V  //finds the length of a string in pixels. thank you calc84maniac!
{Z}+48->{Z}
RectI(X,Y,V+3,r2*7+2
RectI(X+1,Y+1,V+1,r2*7
0->Z
Repeat getKey(9) or getKey(54)
getKey->K
=1-(K=4)+Z->Z
!If +1:r2-1->Z
End
Z^r2->Z
End
Z*7+Y*256+X+V+3->r1:Z
Return

just so you know, this routine *can* fail. Quit and Save have different pixel-lengths on calculator but they'd both be represented as 4Quit and 4Save in my routine.since Save is larger than Quit, make sure you put 4Save as an argument before 4Quit in the parameter list.

also, if you want to use more than 4 options you can group them into categories and call the routine more than once. the next logical placement for a menu after selection is stored into r1 for convenience.

alright, so i decided i'm actually going to do something with this. first thing is i need suggestions on the in-editor menu. it'll look, generally, as the attached picture. hopefully it's intuitive enough. you select an option, and a submenu comes up (that's what the dashes indicate). note that under the File tab, after you select New or Open and a size, the Monochrome, 3Lvl Gray, 4Lvl Gray and Masked submenu is implied. anyway, what are some suggestions for it? for example, for the Turn menu should i have it be Clockwise and CC, or Right and Left? i'm leaning to Right and Left because CC is too short but Counterclockwise is too long.

alright well.. i read through this topic but i still don't know what you're trying to do, besides create a level (which is too general).

-what's its height?
-what's its width?
-how many tiles are there?
-is this a level editor?
-does it need to smoothscroll, or can it scroll by tiles?
-are there any "special" tiles that correspond with each other?

or am i completely off base?

bump.
