Function Documentation

tiles_at()

void tiles_at	(	Environment *	_environment,
		int	_address )

Emit ASM code for TILES AT [int]xx.

This function allows you to set the starting address, in memory, for the tiles (for textual mode) and it is the version that is used when the memory is given as a direct number (i.e.: $8400). The input parameter is decoded and declined according to the hardware limits. So it is not said that exactly the given address is set.

On some machine calling this instruction will define the special variable:

• tilees_address (VT_ADDRESS) - the starting address of text memory

Parameters

_environment	Current calling environment
_address	Address to use

tiles_at_var()

void tiles_at_var	(	Environment *	_environment,
		char *	_address )

Emit ASM code for TILES AT [expression].

This function allows you to set the starting address, in memory, for the tiles (for textual mode) and it is the version that is used when the memory is given as an expression. The input parameter is decoded and declined according to the hardware limits. So it is not said that exactly the given address is set.

On some machine calling this instruction will define the special variable:

• tiles_address (VT_ADDRESS) - the starting address of text memory

Parameters

_environment	Current calling environment
