Within a state, define transitions (jumps) to other states. Each
jump has the form:

To call a subroutine, use the 'call' option:
"\"" fred call=string(dquote)
"\"" fred call=string(dquote)
The subroutine called 'string' is called and the jump to 'fred' is
ignored. The 'dquote' option is passed to the subroutine.
The subroutine itself returns to the caller like this:
"\"" whatever return
"\"" whatever return
If we're in a subroutine, the return is made. Otherwise the jump
to 'whatever' is made.
