  12 C 1998-09-03  IREDELL
  13 C
  14 C USAGE:  CALL FPARSEI(CARG,MARG,KARG)
  15 C
  16 C   INPUT ARGUMENT LIST:
  17 C     CARG     - CHARACTER*(*) STRING OF ASCII DIGITS TO PARSE.
  18 C                INTEGERS MAY BE SEPARATED BY A COMMA OR BY BLANKS.
  19 C     MARG     - INTEGER MAXIMUM NUMBER OF INTEGERS TO PARSE.
  20 C
  21 C   OUTPUT ARGUMENT LIST:
  22 C     KARG     - INTEGER (MARG) NUMBERS PARSED.
  23 C                (FROM 0 TO MARG VALUES MAY BE RETURNED.)
  24 C
  25 C REMARKS:
  26 C   TO DETERMINE THE ACTUAL NUMBER OF INTEGERS FOUND IN THE STRING,
  27 C   KARG SHOULD BE SET TO FILL VALUES BEFORE THE CALL TO FPARSEI AND
  28 C   THE NUMBER OF NON-FILL VALUES SHOULD BE COUNTED AFTER THE CALL.
