Hi Doron,

You can get around this limitation by using macro substitution. Something like
lcFiledLIst = "Filed1, IIF(filed2, ...), .."
lcFrom = "From Mytable"
lcJoin = "JOIN ..."
lcWhere = "Where ...."
lcGroupBy = ...
lcOrderBy = ...

SELECT &lcFiledLIst &lcFrom ;
  &lcJoin ;
  &lcWhere ;
  &lcGroupBy ;
  &lcOrderBy ;
INTO CURSOR ResultCursor
AS you can see the select command is much shorter than 8,192 characters. Just remember that each macro substitution is limited to 8,192 characters also.
