AmigaDOS Inside and Out

As you can see the changes affect more than the output. The alias

command can produce many other changes. Alias Alias Alias Alias

4. Print a file on the printer. At the same time the computer should still be available for use. The file should print in the background. Alias Print run copy to prt:

[]

clone

The brackets act as placeholders for the parameters entered with

print. The new command must be given the name of the file it should print out. For example: Print sys:s/startup-sequence

5. Here is a command that makes a file "invisible" so that it isn't displayed when aDlRorLlST command is EXECUTEd. The hide command hides the specified file from these commands:

Alias Hide protect

[]

+h

The PROTECT command sets the h status bit of the file. The

computer must have at least Kickstart 1.3 to use this command. This h bit is ignored when Kickstart 1.2 is used.

6. As in example 5, the status bit s can be set. The following line must be entered:

Alias SBit protect

+s

When the s bit is set you can EXECUTE a script file without invoking the Execute command.
