COMMAND NAME:

        POP

USAGE:

        POP
        POP <expression>
        POP ALL

        The POP command removes one or more entries from the top of the
        context stack and begins executing in the context uncovered by the
        pop operation.  POP, without any arguments, pops off contexts until
        the next interactive context is uncovered.  If you supply a numeric
        argument then that argument tells how many contexts to pop.

        POP ALL pops all the contexts off the stack (except for the first
        interactive one).  In addition it clears all entries from the symbol
        table and cleans out some internal SCL data structures.  POP with a
        negative argument is equivalent to POP ALL. POP 1 is equivalent to
        RESUME.
