Function Documentation

colormap_at()

void colormap_at	(	Environment *	_environment,
		int	_address )

Emit ASM implementation for COLORMAP AT [int] instruction.

This function allows you to set the starting address, in memory, for the colormap 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:

• COLORMAPADDRESS (VT_ADDRESS) - the starting address of colormap memory

Parameters

_environment	Current calling environment
_address	Address to use

colormap_at_var()

void colormap_at_var	(	Environment *	_environment,
		char *	_address )

Emit ASM implementation for COLORMAP AT [expression] instruction.

This function allows you to set the starting address, in memory, for the colormap 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:

• colormapAddress (VT_ADDRESS) - the starting address of colormap memory

Parameters

_environment	Current calling environment
_address	Address to use
