# joy semantics in F

    i said earlier that it was a trivial matter to change the way F

    handles names (viz. by leaving the value associated with the name

    on the stasck) to conform to the way Joy handles them:  retrieve

    the value and disquote (execute) it.  to make sure that was true,

    i added a switch in the F interpreter which controls name-

    evaluation, and then modified the F prelude accordingly:

      wherever a name is concatenated with "!", elide the "!"

      otherwise, replace the name "xyz" with "[xyz []]."

    the second condition is a verbose F/Joy-neutral way of

    retrieving the value of the name xyz.

    the two preludes are:
