8.3.4.1 File Attributes
A feature of program files is the file attribute. Table CR1000 File Attributes (p. 383)
lists available file attributes, their functions, and when attributes are typically
used. For example, a program file sent with the support software Program Send
(p. 524)
command, runs a) immediately ("run now"), and b) when power is cycled
on the CR1000 ("run on power-up'). This functionality is invoked because
Program Send
(p. 524) sets two CR1000 file attributes on the program file, i.e.,
Run Now and Run on Power-up. When together, Run Now and Run on Power-
up are tagged as Run Always.
Note Activation of the run-on-power-up file can be prevented by holding down
the Del key on the CR1000KD Keyboard Display while the CR1000 is powering
up.
