Table 8-12 lists the information displayed at a TINET terminal:
Steps of Example Program
The basic flow of the example program is:
1. The tutorial masks are written to all terminals in the network.
2. The network is polled.
3. When a polled terminal responds with data, each field in the message is checked to
see that it was entered correctly.
If all fields were entered correctly, the credit check is made, the result of the credit
check is displayed on the terminal, and the tutorial mask is rewritten to the terminal.
If one or more fields were entered incorrectly, a partial tutorial mask is constructed
and written to the terminal. This mask is used to direct the terminal operator to re-
enter the invalid fields. (The valid fields are saved by the program.)
4. The network is again polled.
Figure 8-8
shows the programming example sequence.
