As already seen you can declare namespaces with the namespace directive. When declared it places a symbol inside the scope the parent namespace so the labels inside can be accessed as local fields of the namespace symbol:
.namespace vic {
.label borderColor = $d020
.label backgroundColor0 = $d021
.label backgroundColor1 = $d022
.label backgroundColor2 = $d023
}
lda #0
sta vic.backgroundColor0
sta vic.borderColor
Namespaces are normally used to make sure that code in a source file (Like a library) is not colliding with other parts of the code. For this, Place the filenamespace directive at the top of the file and everything after that is placed in the desired namespace:
/* FILE 0 */
jsr part1.init
jsr part1.exec
jsr part2.init
jsr part2.exec
rts/* FILE 1 */
.filenamespace part1
init:
...
rts
exec:
...
rts
/* FILE 2 */
.filenamespace part2
init:
...
rts
exec:
...
rts
