C>
C> @param[in] CARG character*(*) string of ascii digits to parse.
C> Integers may be separated by a comma or by blanks.
C> @param[in] MARG integer maximum number of integers to parse.
C>
C> @param[out] KARG integer (MARG) numbers parsed.
C> (from 0 to MARG values may be returned.)
C>
C> @note To determine the actual number of integers found in the string,
C> KARG should be set to fill values before the call to FPARSEI() and
C> the number of non-fill values should be counted after the call.
