You can make an array out of this:
sequence a
 a = repeat(5,2) -- sets up 5 "a"s which are all set to equal 2

Then you reference them as a[1]   a[4]  etc.

Type checking does slow down your program, but the line a=0 above
will do nothing. The assignment a=0 only changes the copy of atom a
which is local to this routine. The value of the real variable is not changed.

i.e.
atom0 myatom

myatom = 56
after type checking, myatom will still equal 56.
