for(&x,1,1,subreccount())

show(field('PartNum'))

moveto(1.5,&current.y)

show(field('PartDesc'))

moveto(4.5,&current.y)

show(field('Qty'))

moveto(5.5,&current.y)

show(field('UnitPrice'))

moveto(6.5,&current.y)

show(field('Total'))

moveto(0,&current.y+.25)

endfor()

moveto(6.5,8)

show(floattostr(&tot))
