===== SYNTAX =====
SCREEN #mode
SCREEN #type, #colorset
... = SCREEN
==== PURPOSE ====
The ''SCREEN'' command allows to select a specific hardware-dependent
screen mode. Every target has a specific list of modes. Normally,
these modes are selected by describing resolution and color depth.
This is another way to select graphical modes.
Moreover, there is another syntax for SCREEN. The second syntax
allow to select the type and color scheme. Type is ''0'' for the text
screen and ''1'' for the high resolution screen, while the color
scheme depends on target.
Retrieves a bitmask with screen characteristics, such as whether or
not TILE or BITMAP mode is available.
^ BIT POSITION ^ SYMBOL ^ MEANING ^
| 0 | TILEMAP | Is tilemap native? |
| 1 | BITMAP | Is bitmap native? |
This can be verified with a simple bitwise comparison.
==== EXAMPLE ====
SCREEN #1
SCREEN #1, #0
IF SCREEN IS TILEMAP THEN: PRINT "tilemap is native!": ENDIF
