Table deduction headers can be queried like any other deduction header. The only way to access the detail lines of a table deduction is to first have the deduction header displayed. This means that the table deduction header must be queried before access to the table detail is allowed. After finding the deduction header, the NEXT button <F7> allows access to the table entries. Just pushing the FIND NEXT button <F3> repeatedly at this point displays each line entry in succession. The QUERY button <F2> can be used to specify a particular entry to be found. Press the NEXT button <F7> again to switch back to the deduction header screen.
