/// Replace a marker with a character string.
///
/// # Brief I/O
///
/// ```text
/// VARIABLE I/O DESCRIPTION
/// -------- --- --------------------------------------------------
/// IN I Input string.
/// MARKER I Marker to be replaced.
/// VALUE I Replacement string.
/// OUT O Output string.
/// ```
///
/// # Detailed Input
///
/// ```text
/// 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 the replacement character string.
///
/// Leading and trailing blanks in VALUE are NOT significant:
/// the portion of VALUE that is substituted for MARKER
/// extends from its first non-blank character to its last
/// non-blank character.
///
/// However, if VALUE is blank, a single blank is substituted
/// for the first occurrence of MARKER.
/// ```
///
/// # Detailed Output
///
/// ```text
/// OUT is the string obtained by substituting VALUE (leading and
/// trailing blanks excepted) for the first occurrence of
/// MARKER in the input string.
///
/// OUT and IN must be identical or disjoint.
/// ```
///
/// # Exceptions
///
/// ```text
/// 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.)
///
/// 3) If VALUE is blank, a single blank is substituted for the
/// first occurrence of MARKER.
/// ```
///
/// # Particulars
///
/// ```text
/// 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 )
/// REPML ( Replace marker with logical value )
/// REPMCT ( Replace marker with cardinal text )
/// REPMOT ( Replace marker with ordinal text )
/// ```
///
/// # Examples
///
/// ```text
/// The numerical results shown for this example may differ across
/// platforms. The results depend on the SPICE kernels used as
/// input, the compiler and supporting libraries, and the machine
/// specific arithmetic implementation.
///

/// replace a marker within a string with a character string
/// value.
