SET-WORMHOLE-ENTRY-CODE
sets the wormhole entry code in a wormhole status object
Major Section: MISCELLANEOUS
General Form: (set-wormhole-entry-code whs code)
See wormhole. Whs should be a well-formed wormhole status and code
should be :ENTER or :SKIP. This function returns a new status with
the specified entry code but the same data as whs. It avoids unnecessary
consing if the entry code for whs is already set to code. This
function does not affect state or a wormhole's hidden status. It just
returns a (possibly) new status object suitable as the value of the
lambda expressions in wormhole-eval and wormhole.
