symbol-name

    Specifies a symbol to be identified. A valid symbol name is
    a single identifier or a label name of the form %LABEL n,
    where n is an integer. Compound names such as RECORD.FIELD
    or ARRAY[1,2] are not valid. If you specify the asterisk (*)
    wildcard character by itself, all symbols are listed. You can use
    the wildcard within a symbol name.

 scope

    Specifies the name of a module, routine, or lexical block, or a
    numeric scope. It has the same syntax as the scope specification
    in a SET SCOPE command and can include path-name qualification.
    All specified scopes must be in set modules in the current image.

    The SHOW SYMBOL command displays only those symbols in the RST
    for the current image that both match the specified name and
    are declared within the lexical entity specified by the scope
    parameter. If you omit this parameter, all set modules and the
    global symbol table (GST) for the current image are searched
    for symbols that match the name specified by the symbol-name
    parameter.
