In order to optimize the display of data and execution of transactions,
design simple screens and simple transactions using the following
rules:
- Avoid placing a lot of information into a small space. This ensures
more rapid transaction time and enables the end user to parse data
visually more quickly.
- Because of the reduced screen size, if you need to display a lot
of data, the display of data may need to be altered to accommodate
the amount of data. In this case, the data must be persisted from
one screen to the next before finally being posted. For small screens,
use the TEMPQ utilities to pass data between screens.
- The TempQ utilities enables you to persist and pass data from
one screen to the next. For information on the TempQ utilities, see

- Provide text on one line and the data field on another line to
accommodate for internationalization requirements.
- Validate fields only when necessary in order to optimize transaction
execution time.
- Choose fast or templatized APIs that return exactly the correct
type of information needed in order to optimize transaction execution
time.
