Title

    switch --   Specifiy corresponding values to evaluated cases (more
                  efficient than consecutive if statements)


Syntax

        switch {anything} , cases(string) values(string)

    options                Description
    -------------------------------------------------------------------------
      cases(string)        the possible cases given to {opth switch},
                             separated by a space.
      values(string)       the matching values (in corresponding order) to
                             the cases supplied, separated by a space.

Description

    switch matches a given variable case to a given case-value set and stores
    the result (the matching value) in a local variable called switch_return.
    If no match is made, the local variable switch_return is set to (string)
    no_swatch.

    . switch _8A, cases(_8A 50 _$_) values(1 2 3)
    switch matched _8A to a value of 1
    ---------------------------------------------------------------------------
    . switch 100, cases(_8A 50 _$_) values(1 2 3)
