Using select statement from input file with DB2 EXPORT

I'm successfully doing an export using the following shell script

#!/bin/ksh

db2 Connect to ALIAS user USERNAME using PASSWORD

db2 "EXPORT TO result.dat OF DEL MODIFIED BY NOCHARDEL COLDEl| select memrecno, memidnum from mpi_memhead fetch first 10 rows only"

db2 terminate

Select allOpen in new window

Rather than having my select statement where it is, I'd like to specify a file with the select statement.  My googling isn't helping :-/

Thanks in advance.
