Agnes,

Edward's suggestion is one way, another way is :

  PARAMETERS  pddate
  LOCAL lcReturn
  lcReturn = ""
  lcReturn = ALLTRIM(STR(YEAR(pddate))) + "-" ;
    + PADL(MONTH(pddate),2, "0") + "-"  ;
    + PADL(DAY(pddate),2,"0")
  ENDIF
  RETURN lcReturn

not tested, just changed from my code. Mine said no dashes in format YYYYMMDD.
