You just write the name of the variable:

lds r24, name_of_your_variable

If you want to be nice to the reader of your program, you declare
it external before:

..extern name_of_your_variable

However, that's not strictly necessary; any symbol the assembler
encounters it doesn't know about yet, it enters into the symbol table
as `undefined external'.  In effect, that's the same as the .extern
statement is going to do.
