"Undocumented" REXX functions


The following REXX functions to work with DBCS mixed Strings are only 
documented in the IBM: OS/2 2.0 Procedures Language/2 Reference Manual and 
in the Object-Oriented REXX online documentation: 
   *  DBADJUST 
   *  DBBRACKET 
   *  DBCENTER 
   *  DBLEFT 
   *  DBRIGHT 
   *  DBRLEFT 
   *  DBRRIGHT 
   *  DBTODBCS 
   *  DBTOSBCS 
   *  DBUNBRACKET 
   *  DBVALIDATE 
   *  DBWIDTH 
 
 Well, for the "normal" REXX programmer only two of these functions are 
 interesting (The functions also work with SBCS strings):   
 Name       DBRLEFT( string, n {,option} ) 
 Function   Delete n chars beginning with the first char 
 Example    DBRLEFT( "ABCDEFG", 2 ) gives "CDEFG"
 Note       The parameter option is only needed for DBCS strings)
            For SBCS strings you should not use this parameter.
 
 Name       DBRRIGHT( string, n {,option} ) 
 Function   Delete n chars beginning with the last char 
 Example    DBRRIGHT( "ABCDEFG", 3 ) gives "ABCD"
 Note       The parameter option is only needed for DBCS strings)
            For SBCS strings you should not use this parameter.
