RPGILESQL PGM

 Hello,
In RPGILE pgm I am trying to select records within date range entered from the
screen. It is 4 separate fields in the file (SNSCC, SNSYY, SNSMM, SNSDD). I am
trying following code, but it is does not work correctly. I was trying to
combine the date in one field, but it did not work either. I do not use SQL,
any idea will be appreciated. Thank you.

 C/EXEC SQL
 C+ DECLARE C1 CURSOR  FOR
 C+ SELECT all *   FROM PFfile

 C+ AND SNSCC >=:FC AND SNSCC <=:TC
 C+ AND SNSYY >=:FY AND SNSYY <=:TY
 C+ AND SNSMM >=:FM AND SNSMM <=:TM
 C+ AND SNSDD >=:FD AND SNSDD <=:TD
