/* $ Detailed_Input */

/*     IN             is an arbitrary character string. */

/*     MARKER         is an arbitrary character string. The first */
/*                    occurrence of MARKER in the input string is */
/*                    to be replaced by VALUE. */

/*                    Leading and trailing blanks in MARKER are NOT */
/*                    significant. In particular, no substitution is */
/*                    performed if MARKER is blank. */

/*     VALUE          is an arbitrary double precision number. */

/*     SIGDIG         is the number of significant digits with */
/*                    which VALUE is to be represented. SIGDIG */
/*                    must be greater than zero and less than 15. */

/* $ Detailed_Output */


/*     OUT            is the string obtained by substituting the text */
/*                    representation of VALUE for the first occurrence */
/*                    of MARKER in the input string. */

/*                    The text representation of VALUE is in scientific */
/*                    notation, having the number of significant digits */
/*                    specified by SIGDIG.  The representation of VALUE */
/*                    is produced by the routine DPSTR; see that routine */
/*                    for details concerning the representation of */
/*                    double precision numbers. */

/*                    OUT and IN must be identical or disjoint. */

/* $ Parameters */

/*     MAXLDP         is the maximum expected length of the text */
/*                    representation of a double precision number. */
/*                    23 characters are sufficient to hold any result */
/*                    returned by DPSTR. (See $Restrictions.) */

/* $ Files */

/*     None. */

/* $ Exceptions */

/*     Error Free. */

/*     1) If OUT does not have sufficient length to accommodate the */
/*        result of the substitution, the result will be truncated on */
/*        the right. */

/*     2) If MARKER is blank, or if MARKER is not a substring of IN, */
/*        no substitution is performed. (OUT and IN are identical.) */

/* $ Particulars */

/*     This is one of a family of related routines for inserting values */
/*     into strings. They are typically to construct messages that */
/*     are partly fixed, and partly determined at run time. For example, */
/*     a message like */

/*        'Fifty-one pictures were found in directory [USER.DATA].' */

/*     might be constructed from the fixed string */

/*        '#1 pictures were found in directory #2.' */

/*     by the calls */

/*        CALL REPMCT ( STRING, '#1', N_PICS,  'C', STRING ) */
/*        CALL REPMC  ( STRING, '#2', DIR_NAME,     STRING ) */

/*     which substitute the cardinal text 'Fifty-one' and the character */
/*     string '[USER.DATA]' for the markers '#1' and '#2' respectively. */

/*     The complete list of routines is shown below. */

/*        REPMC    ( Replace marker with character string value ) */
/*        REPMD    ( Replace marker with double precision value ) */
/*        REPMF    ( Replace marker with formatted d.p. value ) */
/*        REPMI    ( Replace marker with integer value ) */
/*        REPMCT   ( Replace marker with cardinal text) */
/*        REPMOT   ( Replace marker with ordinal text ) */

/* $ Examples */

/*     1. Let */

/*          IN = 'Invalid operation value.  The value was #.' */

/*        Then following the call, */

/*           CALL REPMD ( IN, '#', 5.0D1, 2, IN  ) */

/*        IN is */

/*           'Invalid operation value.  The value was 5.0E+01.' */


/*     2. Let */

/*          IN = 'Left endpoint exceeded right endpoint.  The left */
/*                endpoint was: XX.  The right endpoint was: XX.' */

/*        Then following the call, */

/*           CALL REPMD ( IN, '  XX  ',  -5.2D-9, 3, OUT ) */

/*         OUT is */

/*           'Left endpoint exceeded right endpoint.  The left */
/*            endpoint was: -5.20E-09.  The right endpoint was: XX.' */


/*     3. Let */

/*          IN = 'Invalid operation value.  The value was #.' */

/*        Then following the call */

/*           CALL REPMD ( IN, '#', 5.0D1, 100, IN  ) */

/*        IN is */

/*            'Invalid operation value.  The value was */
/*             5.0000000000000E+01.' */

/*        Note that even though 100 digits of precision were requested, */
/*        only 14 were returned. */


/*     4. Let */

/*           NUM    = 23 */
/*           CHANCE = 'fair' */
/*           SCORE  = 4.665D0 */

/*        Then following the sequence of calls, */

/*           CALL REPMI ( 'There are & routines that have a '  // */
/*          .             '& chance of meeting your needs.'    // */
/*          .             'The maximum score was &.', */
/*          .             '&', */
/*          .             NUM, */
/*          .             MSG  ) */

/*           CALL REPMC ( MSG, '&', CHANCE, MSG ) */

/*           CALL REPMD ( MSG, '&', SCORE, 4, MSG ) */

/*        MSG is */

/*           'There are 23 routines that have a fair chance of */
/*            meeting your needs.  The maximum score was 4.665E+00.' */

/* $ Restrictions */

/*     1) The maximum number of significant digits returned is 14. */

/*     2) This routine makes explicit use of the format of the string */
/*        returned by DPSTR; should that routine change, substantial */
/*        work may be required to bring this routine back up to snuff. */
