I think you can get away with using ScreenID() but only when the debugger off

ScreenID() works only if a screen is open, which is not exactly what i was looking for.

I think adding sprite.lib to the depedencies of the desc-file of the userlib should work,
or Import "Sprite.lib" : EndImport", but not tested,

but i would not call InitSpite in the userlib!

why not? as long as its not inside the AttachProcess() it should be perfectly fine.

A userlib isn't a dll..

Why not save yourself the hassle and just say in your manual that those commands must be called before using the commands in your lib? Why reinvent the wheel?

@netmaestro
i mean the tailbite *_Init()

@C64
because i dont want them to call it at all?! and since no one reads TFM, i just want to be on the safe side.
