This looks like deja vu all over again. Here is the
answer: Ain't no way, no how!

But..., I got about this close:

FUNCTION MAGIC, file
number = 0
ok = EXECUTE(file + ' = 0')
RESTORE, file
RETURN, number
END

IDL> a = 10
IDL> number = a
IDL> Save, a, number, Filename='a'
IDL> b = 'a'
IDL> c = Magic(b)
IDL> IF c EQ 10 THEN Print, "It's magic!"

It's magic!
