Function Documentation

textmap_at()

void textmap_at	(	Environment *	_environment,
		int	_address )

Emit ASM code for TEXTMAP AT [int]xx.

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

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

Parameters

_environment	Current calling environment
_address	Address to use

textmap_at_var()

void textmap_at_var	(	Environment *	_environment,
		char *	_address )

Emit ASM code for TEXTMAP AT [expression].

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

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

Parameters

_environment	Current calling environment
_address	Expression with address to use
