SCREEN TILES WIDTH

SYNTAX

   = SCREEN TILES WIDTH

PURPOSE

This function allows you to obtain the width of the current screen, expressed in tiles. A tile is a box of pixels that can be addressed elementary by a specific screen code. Normally, it is used in “text mode”, since each box is a character. The width depends on the currently selected graphics mode, and it can change at runtime.

There is also a compile-level function for this keyword, which is called when the value is used to initialize a constant. In this case, the value is that taken from inspecting the instructions at the time of compilation.

It can also be abbreviated to the statement TILES WIDTH.

EXAMPLE

  currentWidth = SCREEN TILES WIDTH
