Tandy 1000 Owner's Manual

Operation
Result codes
Result codes are displayed in either numeric or verbal code after the com-
mand line is executed.
Command
Q determines whether the result codes will be displayed. When
Q1 is selected, the result codes will not be displayed. When QO is selected,
you can see the codes
on the screen. Command V selects either numeric (VO)
or verbal (Vl) codes.
The default values of these controls are fixed by DIP switches. For example,
when DIP Switch
4 is set to ON, the result codes do not appear on the screen
unless
QO is entered from the keyboard. (Refer to Chapter 1, DIP switches).
