+
+  The <tt/.ADDRSIZE/ function is used to return the interal address size 
+  associated with a symbol. This can be helpful in macros when knowing the address 
+  size of symbol can allow for custom instructions.
+
+  Example:
+
+  <tscreen><verb>
+        .macro myLDA foo
+
+  	        .if .ADDRSIZE(foo) = 1
+  	          	        ;do custom command based on zeropage addressing:
+  	          	        .byte .A5h, foo
+  	        .elseif .ADDRSIZE(foo) = 2
+  	          	        ;do custom command based on absolute addressing:
+  	          	        .byte .ADh, foo
+  	        .elseif .ADDRSIZE(foo) = 0
+  	          	        ; no address size define for this symbol:
+  	          	        .out .sprinft("Error, address size unknown for symbol %s", .string(foo))
+  	        .endif
+        .endmacro
+  </verb></tscreen>
+
+  This command is new and must be enabled with the <tt/.FEATURE addrsize/ command.
