#### 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'.

                   `marker' is case-sensitive.

                   Leading and trailing blanks in `marker' are NOT
                   significant. In particular, no substitution is
                   performed if `marker' is blank or empty.

       value       is an arbitrary logical value, either SPICETRUE or
                   SPICEFALSE.

       rtcase      indicates the case of the replacement text. `rtcase' may
                   be any of the following:

                      rtcase    Meaning        Output values
                      ------    -----------    ---------------
                      U, u      Uppercase      "TRUE", "FALSE"

                      L, l      Lowercase      "true", "false"

                      C, c      Capitalized    "True", "False"

       outlen      is the maximum allowed length of the output string `out'.
                   This length must be large enough to hold the output string
                   plus the null-terminator character. If the output string
                   is expected to have N characters, `outlen' should be at
                   least N+1.
#### Detailed_Output
       out         is the string obtained by substituting the text
                   representation of `value' for the first occurrence of
                   `marker' in the input string.

                   `out' and `in' must be disjoint.
#### Parameters
       None.
#### Exceptions
       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 empty, or if `marker' is not a substring of
           `in', this routine leaves the input string unchanged, except that
           trailing blanks will be trimmed. This case is not considered an error.

       3)  If the value of `rtcase' is not recognized, the error
           SPICE(INVALIDCASE) is signaled by a routine in the call tree
           of this routine. `out' is not changed.

       4)  If any of the `in' or `marker' input string pointers is null,
           the error SPICE(NULLPOINTER) is signaled.

       5)  If the `out' output string pointer is null, the error
           SPICE(NULLPOINTER) is signaled.

       6)  If the `out' output string has length less than two
           characters, the error SPICE(STRINGTOOSHORT) is signaled, since
           the output string is too short to contain one character of
           output data plus a null terminator.
#### Files
       None.
#### Particulars
       This is one of a family of related routines for inserting values
       into strings. They are typically used 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

          repmct_c ( string, "#1",       51, "C", LENTMP, tmpstr );
          repmc_c  ( tmpstr, "#2", "[USER.DATA]", LENSTR, 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_c    ( Replace marker with character string value )
          repmd_c    ( Replace marker with double precision value )
          repmf_c    ( Replace marker with formatted d.p. value   )
          repmi_c    ( Replace marker with integer value          )
          repml_c    ( Replace marker with logical value          )
          repmct_c   ( Replace marker with cardinal text          )
          repmot_c   ( Replace marker with ordinal text           )
#### Examples
       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.

       1) The following example illustrates the use of repml_c to replace
          a marker within a string with the text representation of a
          logical value.

          Example code begins here.

          /.
             Program repml_ex1
          ./
          #include <stdio.h>
          #include <string.h>
          #include "SpiceUsr.h"

          int main( )
          {

             /.
             Local parameters.
             ./
             #define STRLEN       81

             /.
             Local variables.
             ./
             SpiceChar            instr  [STRLEN];
             SpiceChar            marker [STRLEN];
             SpiceChar            outstr [STRLEN];

             /.
             1. Uppercase
             ./
             strncpy( marker, "#", 2 );
             strncpy( instr, "Invalid value. The value was:  #.", 34 );

             repml_c ( instr, marker, SPICEFALSE, 'U', STRLEN, outstr );

             printf( "Case 1: Replacement text in uppercase.\n" );
             printf( "   Input : %s\n", instr );
             printf( "   Output: %s\n", outstr );
             printf( "\n" );

             /.
             2. Lowercase
             ./
             strncpy( marker, " XX ", 5 );
             strncpy( instr, "Invalid value. The value was:  XX.", 35 );

             repml_c ( instr, marker, SPICETRUE, 'l', STRLEN, outstr );

             printf( "Case 2: Replacement text in lowercase.\n" );
             printf( "   Input : %s\n", instr );
             printf( "   Output: %s\n", outstr );
             printf( "\n" );

             /.
             2. Capitalized
             ./
             strncpy( marker, "#", 2 );
             strncpy( instr, "Invalid value. The value was:  #.", 34 );

             repml_c ( instr, marker, SPICEFALSE, 'c', STRLEN, outstr );

             printf( "Case 3: Replacement text capitalized.\n" );
             printf( "   Input : %s\n", instr );
             printf( "   Output: %s\n", outstr );

             return ( 0 );
          }

          When this program was executed on a Mac/Intel/cc/64-bit
          platform, the output was:

          Case 1: Replacement text in uppercase.
             Input : Invalid value. The value was:  #.
             Output: Invalid value. The value was:  FALSE.

          Case 2: Replacement text in lowercase.
             Input : Invalid value. The value was:  XX.
             Output: Invalid value. The value was:  true.

          Case 3: Replacement text capitalized.
             Input : Invalid value. The value was:  #.
             Output: Invalid value. The value was:  False.
