Writes all cached attribute data to the terminal screen. In an operation, attribute
data can be assigned using write commands like DefaultValue
or TransmitToAttr. An operation can call
the UpdateAttributes command for all attributes that have assigned data. This
command is used in conjunction with the Cache
all attribute writes check box on the General
tab of the Advanced Entity Properties dialog box.
- By default, an UpdateAttribute command will be inserted in each generated
operation when Cache all attribute writes is selected.
- This feature is specifically designed for character
mode applications as a solution for managing the order of screen updates.
When attribute data assignments are arbitrarily mixed between an operation
and a Host Integrator API, the order in which data is actually written to
the terminal can be important to the host application.
