Underflow and Overflow conditions for BTEQ

Hello All,
I'm trying to import a tab delimited file into a table.
Overflow condition = number of delimited values of record in import file > number of columns in table
 Behavior – BTEQ silently ignoring the overflow columns that are at the end of the record.
Underflow condition = number of delimited values of a record in import file < number of columns in table
 Behavior – returns Failure 2673.
Is there any BTEQ command that i can mention in load script so that BTEQ returns an error for overflown records as well?
Thanks, Ram.
