Replace a marker with the text representation of a cardinal number.
VARIABLE I/O DESCRIPTION -------- --- -------------------------------------------------- in I Input string. marker I Marker to be replaced. value I Replacement value. repcase I Case of replacement text. lenout I Available space in output string. out O Output string. MAXLCN P is the maximum expected length of any cardinal 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 the text representation of the cardinal number value. 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 integer. repcase indicates the case of the replacement text. repcase may be any of the following: repcase Meaning Example ------- ----------- ----------------------- U, u Uppercase ONE HUNDRED FIFTY-THREE L, l Lowercase one hundred fifty-three C, c Capitalized One hundred fifty-three lenout is the allowed length of the output string. This length must large enough to hold the output string plus the terminator. If the output string is expected to have x characters, lenout should be at least x + 1.
out is the string obtained by substituting the text representation of the cardinal number value for the first occurrence of marker in the input string. out and in must be identical or disjoint.
MAXLCN is the maximum expected length of any cardinal text. 145 characters are sufficient to hold the text representing any value in the range ( -10**12, 10**12 ) An example of a number whose text representation is of maximum length is - 777 777 777 777
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', LENOUT, string ); repmc_c ( string, "#2", "[USER.DATA]", LENOUT, 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 ) repmct_c ( Replace marker with cardinal text ) repmot_c ( Replace marker with ordinal text )
The following examples illustrate the use of repmct_c to replace a marker within a string with the the cardinal text corresponding to an integer. Uppercase --------- Let marker == "#" in == "Invalid command. Word # was not recognized." Then following the call, #include "SpiceUsr.h" . . . #define LENOUT 201 . . . repmct_c ( in, "#", 5, 'U', LENOUT, in ); in is "Invalid command. Word FIVE was not recognized." Lowercase --------- Let marker == " XX " in == "Word XX of the XX sentence was misspelled." Then following the call, #include "SpiceUsr.h" . . . #define LENOUT 201 . . . repmct_c ( in, " XX ", 5, 'L', LENOUT, out ); out is "Word five of the XX sentence was misspelled." Capitalized ----------- Let marker == " XX " in == "Name: YY. Rank: XX." Then following the calls, #include "SpiceUsr.h" . . . #define LENOUT 201 . . . repmc_c ( in, "YY", "Moriarty", LENOUT, out ); repmct_c ( out, "XX", 1, 'C', LENOUT, out ); out is "Name: Moriarty. Rank: One."
1) value must be in the range accepted by subroutine inttxt_. This range is currently ( -10**12, 10**12 ) Note that the endpoints of the interval are excluded.
1) The error SPICE(NULLPOINTER) is signaled if any of the input or output string pointers is null. 2) If the marker string is blank or empty, this routine leaves the input string unchanged, except that trailing blanks will be trimmed. This case is not considered an error. 3) If the output string is too short to accommodate a terminating null character, the error SPICE(STRINGTOOSHORT) is signaled. 4) If out does not have sufficient length to accommodate the result of the substitution, the result will be truncated on the right. 5) If the value of repcase is not recognized, the error will be diagnosed by routines in the call tree of this routine. out is not changed.
