I am using SPT to insert data into as AS400 database. All works fine until I try and add another field of the record to insert. What I think is happening is my insert string is getting too long. How can I use variables to make the string shorter?

My Code:
testthissd = "INSERT INTO drawmstrp (dm_drawing_number,dm_drawing_title,dm_pending_change,dm_date_issued,dm_requester_name1,dm_requester_name2, ;
dm_job_order,dm_project,dm_customer) Values(&nfn,&nf2,&nf3,&nf4,&nf5,&nf6,&nf7,&nf8,&nf9)"
*? testthissd

= SQLSETPROP(gnHandle1n, 'Transactions', 2)
= SQLEXEC(gnHandle1n, testthissd)
