Kick Assembler Manual
Chapter 9. Scopes and Namespaces

To escape the current scope, use @ to reference the root scope. In the following code '@myLabel' access the myLabel label in the root scope:

.label myLabel = 1
{
   .label myLabel = 2

   .print "scoped myLabel="+ myLabel //<-- Returns 2	
   .print "root myLabel="+ @myLabel  //<-- Returns 1
}

The same can be done for functions, macros and pseudo commands. So the following example will print 'root' not 'mySpace':

.function myFunction() { .return "root"}
.namespace mySpace {
   .function myFunction() { .return "mySpace" }
   .print @myFunction()
}

You can also put new entities in the root scope when defining them from within another scope:

   jsr outside_label 
   rts
{
@outside_label:
    
   lda #0
   sta $d020
   sta $d020
   rts
}

or:

{
   .label @x = 1234
   .var @y= "Hello world"
   .const @z= true
}

.print "x="+x
.print "y="+y
.print "z="+z

Or for functions, macros or pseudo commands, here shown in a library file:

#import "mylib.lib"

.print myFunction()
MyMacro()
MyPseudoCommand

/* File mylib.lib */
#importonce
.filenamespace MyLibrary

.function @myFunction() { 
   .return 1
}

.macro @MyMacro() { 
   .print "Macro Called"
}

.macro @MyPseudoCommand { 
   .print "PseudoCommand Called"
}
