    ACL2-pc::retrieve

    (macro) re-enter the proof-builder

    Examples:
    (retrieve associativity-of-permutationp)
    retrieve
    
    General Form:
    (retrieve &optional name)

    Must be used from outside the interactive proof-builder loop. If name (which must be a symbol) is supplied and not nil, this causes re-entry to the interactive proof-builder loop in the state at which save was last executed for the indicated name. (See ACL2-pc::save.) If name is nil or is not supplied, then the user is queried regarding which proof-builder state to re-enter. The query is omitted, however, if there only one proof-builder state is present that was saved with save, in which case that is the one that is used. Also see ACL2-pc::unsave.
