I think there is a slight flaw in this expression. If fld5 is empty, there would be an extra comma at the end. It may not be most efficient, but my modification would be

SUBSTR(IIF(EMPTY(fld1), "", ","+alltrim(fld1)) ;
      + IIF(EMPTY(fld2), "", ","+alltrim(fld2)) ;
      + IIF(EMPTY(fld3), "", ","+alltrim(fld3)) ;
      + IIF(EMPTY(fld4), "", ","+alltrim(fld4)) ;
      + IIF(EMPTY(fld5),"",","+alltrim(fld5)),2)
