------------------------------------------------------------------------------
 Syntax

     REPLRIGHT(<cString>,<cReplacecharacter|
        nReplacecharacter>[<cSearchCharacter|
        nSearchCharacter>]) --> cString

 Arguments

     <cString>  [@]  Designates the string that is processed.

     <cReplacecharacter|nReplacecharacter>  Designates the character that
     replaces the character in <cSearchCharacter|nSearchCharacter> at the end
     of the <cString>.

     <cSearchCharacter|nSearchCharacter>  Designates the character at the
     end of <cString> that is replaced by <cReplacecharacter|
     nReplacecharacter>.  The default value is a space, CHR(32).

 Returns

     The processed <cString> is returned.

 Description

     REPLRIGHT() can be used to exchange all trailing characters in a string
     for any character you choose.

 Note

     .  The return value of this function can be suppressed by
        implementing CSETREF() to save space in working memory.

 Examples

     .  Replace the trailing spaces with dashes:

        ? REPLRIGHT("abcd  ", "-")        // "abcd--"

     .  Replace the trailing dashes with spaces:

        ? REPLRIGHT("abcd--", " ", "-")   // "abcd  "

     .  Replace only the trailing spaces:

        ? REPLRIGHT("   1  ", "-")        // "   1--"
