Converting types into other types
|
||||||
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||||
|
|
||||||
|
Sometimes you need an unsigned word where you have an unsigned byte, or you need some other type conversion.
|
||||||
|
Many type conversions are possible by just writing ``as <type>`` at the end of an expression::
|
||||||
|
|
||||||
|
uword uw = $ea31
|
||||||
|
ubyte ub = uw as ubyte ; ub will be $31, identical to lsb(uw)
|
||||||
|
float f = uw as float ; f will be 59953, but this conversion can be omitted in this case
|
||||||
|
word w = uw as word ; w will be -5583 (simply reinterpret $ea31 as 2-complement negative number)
|
||||||
|
f = 56.777
|
||||||
|
ub = f as ubyte ; ub will be 56
|
||||||
|
|
||||||
|
Sometimes it is a straight 'type cast' where the value is simply interpreted as being of the other type,
|
||||||
|
sometimes an actual value conversion is done to convert it into the targe type.
|
||||||
|
Try to avoid type conversions as much as possible.

Indirect addressing and address-of
|
|
||||||
----------------------------------
|
|
||||||
|
|
||||||
The ``#`` operator is used to take the address of the symbol following it.
|
|
||||||
It can be used for example to work with the *address* of a memory mapped variable rather than
|
|
||||||
the value it holds. You could take the address of a string as well, but that is redundant:
|
|
||||||
the compiler already treats those as a value that you manipulate via its address.
|
|
||||||
For most other types this prefix is not supported and will result in a compilation error.
|
|
||||||
The resulting value is simply a 16 bit word.
|

||||||

||||||

Direct access to memory locations
|
||||||
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||||
|
Normally memory locations are accessed by a *memory mapped* name, such as ``c64.BGCOL0`` that is defined
|
||||||
|
as the memory mapped address $d021.
|
||||||
|
|
||||||
|
If you want to access a memory location directly (by using the address itself), without defining
|
||||||
|
a memory mapped location, you can do so by prefixing the address with ``@``::
|
||||||
|
|
||||||
|
A = @$d020 ; set the A register to the current c64 screen border color ("peek(53280)")
|
||||||
|
@$d020 = 0 ; set the c64 screen border to black ("poke 53280,0")
|
||||||
|
@(vic+$20) = 6 ; you can also use expressions to 'calculate' the address
