Modified Data Tag (MDT)
This feature allows you to specify that only the fields that have been
modified are transmitted to the computer. You do not need to take any
action to use this feature.
Extended Local Edits
This feature allows the terminal to edit information as it is typed onto
the form. You specify the editing you want to be done by entering the
LOCALEDITS command in the field processing specification section of
FORMSPEC.
Relabelling Function Keys
This feature allows you to specify, at form creation or modification
time, those function key labels that will be used during data entry.
Hi-Li can perform function key labeling on all the terminals it sup-
ports.
Security Display Enhancement (SEC ENH)
This feature allows you to inhibit the display of data in certain fields.
When this feature is used, the characters entered at the terminal are
displayed as blanks on the screen.
X.25 Capability
This feature allows X.25 block mode to be used via a PAD interface. When
you use this capability on the HP 2622A, HP 2623A, and HP 2624B
terminals, check the ROMS for auto keyboard lock.
Color Enhancement
This feature allows you to use color for field, error, and window
enhancements with the HP 2397A and HP 2627A terminals.
Terminal Buffer Configuration
When using the HPDSEND, HPDREAD, or HPDPROMPT intrinsics, your system
must have sufficient terminal buffers available for all concurrently
executing terminal I/O operations. The number of terminal buffers on
your system must be at least 150 and it is recommended that you set the
number of terminal buffers to the maximum number shared by all processes
that your system allows. For information about terminal buffers, see
the configuration dialogue in the
MPE/V Systems Operation and Resource
Management Reference Manual
(Part No. 32033-90005).
Recovering From Unexpected Program Interruption
A robust application design that uses the Hi-Li intrinsics will include
a REFRESH function key for every form. The application would implement a
