EDIT: Looks like this was fixed in the SVN.
fxm: __SCREEN does the same as SCREEN, except it apparently goes into fullscreen mode.
As you said, Prime, In "SCREEN", the colorswitch% parameter (second parameter) has nothing to do with full-screen in "-lang qb".
The wiki page says:
# In the -lang qb dialect, the usage is:
Screen [mode] [,[active_page][,[visible_page]]]
I'm not sure if that correctly reflects the compiler, though.. it needs another parameter: the colorswitch%. And, the main part is that it doesn't work correctly anyways! (The screen needs to be white, not black.)
In QBASIC, the actual usage is: (straight from the manual):
Code: Select all
Screen [mode%] [,[colorswitch%] [,[activepage%][,[visiblepage%]]]
That means: "SCREEN 7, , 0, 1" in "-lang qb".
I think it might be a simple problem of only one video page being allocated when "screen" is used in lang qb.
