-@deftypefunx {bool} var_is_plausible_name (const char *@var{name}, bool @var{issue_error})
-Tests @var{name} for validity or ``plausibility.'' Returns true if
-the name is acceptable, false otherwise. If the name is not
-acceptable and @var{issue_error} is true, also issues an error message
-explaining the violation.

-A valid name is one that fully satisfies all of the requirements for
-variable names (@pxref{Tokens,,,pspp, PSPP Users Guide}). A
-``plausible'' name is simply a string whose length is in the valid
-range and that is not a reserved word. PSPP accepts plausible but
-invalid names as variable names in some contexts where the character
-encoding scheme is ambiguous, as when reading variable names from
-system files.
