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
