Not all keys or commands are usable in every display. If a key is
inactive in the current display, it will not appear on the command line
when pressed.
Command Line History
After entering a command, you will notice that the command turns from
white and amber text to gray text. The entered command is now called the
command line history. You cannot manipulate the information in the
command line history, it just shows what command you last entered.
Console Memory
When you turn off your console, the console remembers the cues and all
other show information, so that when you turn the console back on, all the
show information from the previous session is still there. The show
information is stored in RAM (Random Access Memory) and remains there
because an internal battery keeps the RAM active. However, the battery
method is only as fail-safe as the battery itself. If the console does not
remember the previous show, the battery may need to be replaced. For this
reason it is important to backup shows to disk after every session where
significant programming changes occur.
To change the internal battery, see
Appendix C Maintenance .
Record Disk / Load Disk
The current show data can be recorded from RAM onto a standard 3.5"
1.44MB High Density floppy disk for storage. You can then retrieve show
data from the floppy disk.
To record and retrieve show data, see
Chapter 11 Memory Functions
