Getting the SCREEN mode

[TerryRitchie]

For a site called "QB64 Game Programming" it might be better to make a recommendation to use "_NEWIMAGE" instead of "SCREEN" for new programs. "SCREEN" prevails, though for a generic tutorial which must accept importing programs from M$QB or QBasic. ...

While I wrote this I failed to notice "SCREEN" statement was needed anyway combined with "_NEWIMAGE". I was unable to remember "_NEWIMAGE()" is a function, can't do stuff itself that "SCREEN" does! I'm sorry about that.

If there are people typing in programs from old books, meant for QuickBASIC then they must be running DOSBOX, or actually be on a computer old enough to support 16-bit, pre-Windows8. Less likely they would be doing it on QB64. It's because otherwise they would be whining, "Damn it SCREEN 13 is wee too small! How do I make it larger?" LOL why make it larger, so you could appreciate the rough resolution?    This is before the hogs, of the many-inches television screens used as computer viewports, come into mind. In the music-creation world there is a lot of pathetic complaining about too-small GUI's out of programs created in decade-2000. They want to get out of 32-bit so much.

Somebody is going to ask to convert a GUI program done in VBDOS to QB64PE. Then expect it to run on Linux without Wine. Do it yourself bruv!

This "rant" wasn't aimed at anybody in particular.

Why would they need DOSBox? They can simply type the code into QB64 and it will run just fine. Remember, QB64 is nearly 100% compatible with all code written for GWBASIC (line numbers) and QuickBasic. No old computer or DOSBox needed.

And as far as making SCREEN 13 bigger, easy peasy:

SCREEN13& = _NEWIMAGE(320,200,13) ' Work Screen
SCREEN _NEWIMAGE(1024,800,32) ' Graphics Screen
_DEST SCREEN13& ' Switch to work screen
' Draw your graphics and such
_DEST 0 ' Switch to graphics screen
_PUTIMAGE ,SCREEN13& ' Map work screen onto graphics screen
