Validate – The process of checking an Application for mistakes
that will cause problems when it is run. MessageBuilder software
notifies the application designer of any validation errors, since they
must be corrected before the application can be downloaded to a
MessageView terminal. Applications are automatically validated as
part of the Download process, and they may also be validated while
they are being created.

Value Trigger – A message’s number. The Controller may specify
a message number to call up the corresponding message.

Variable – A number or an array of characters whose value in a
message displayed by the MessageView terminal is sent from data in
the Controller, or from the value input by the operator or by an
ASCII Input Device. In MessageBuilder software a variable is
represented by a Placeholder.

Verify – The process by which a MessageView terminal checks an
Application that has been Downloaded to make sure it is designed
for the correct type of terminal.

W –

Workspace – The area of the computer display in which the
MessageBuilder Application is created and edited.

Z –

Zoom – A procedure for enlarging the Terminal View so that it is
larger than the default size.
