l_prcode is the process code (memvar and fieldname) and l_cocode is the company code (memvar and fieldname)

I should have included the entire code. Here is the missing code that should answer your other questions:

lnRelativeColumn = .RelativeColumn
Thisform.LockScreen = .T.
IF lnRelativeColumn = 1
	.ActivateCell( .RelativeRow, 2 )
ELSE	
	.ActivateCell( .RelativeRow, 1 )
ENDIF
.ActivateCell( .RelativeRow, lnRelativeColumn )
Thisform.LockScreen = .F.
SELECT ( .RecordSource )
