DSPPGM

Hi
I ve written so many programs in RPGLE on V5R1....
I have written a simple program ..it is as follows..
*************** Beginning of data
*************************************
fpf100     if   e           k disk
fd1        cf   e             workstn
c     *in03         doweq     *off
c                   exfmt     dsprec
c     sno           setll     pf100
90
c     *in90         ifeq      *off
c                   read      pf100
c                   endif
c                   enddo
c                   seton
lr
------------------------------------------

when iam entering this program name in DSPPGM to see the program
decsription...it is showing that
no. of service programs used are 3...but iam nt using any service
programs in creating this program...Its just dynamic binding
program..Can u please clarify me that why it is showing no.of
service programs as 3,though iam nt using any service
programs?????nt only this other programs also started showing no
of service programs  as 3 or 4 etc which are created
dynamically..
Best Regards to All,
Murali
