Example:
The information in the sample screen below is defined at and sent from the host. It
includes the “AIAG Identifier” – the tag identifying this as an AIAG field – followed
by the mode, in this case Mode 0, and finally, the “AIAG Prefix” – I.
Figure 6.7 AIAG Field Sent From The Host
When the information arrives at the terminal screen, the appropriate AIAG field for
the scanned information is located using the “AIAG Identifier”. Because Mode 0
was set at the host, the “AIAG Prefix” – I – is displayed on the terminal screen, and
when this screen is completed, the prefix will be sent back to the host.
Figure 6.8 AIAG Field Sent To The Terminal
Visible Match Character
By inserting a special ASCII character directly before an entry field, the application
program distinguishes a “match field” from an entry field. For example, suppose an
angle bracket “
>
” is defined for visible match fields. Inserting “
>
” immediately
preceding the entry field identifies it as a match field, as illustrated below.
