Most commands can be aborted by depressing Control-C.
Nearly everything is case independent.
To use a disk command simply type its name after the prompt, the
same way as you would do in other shells. The first part of the input
up to the first space is interpreted as commandname. It is searched
for (in this order) :
 1. in the  alias  list
 2. in the internal (builtin) command list (see  COMMAND OVERVIEW )
 3. in the  resident  command list
 4. in the current directory (see  CD )
 5. in the  command search path 
and, if it is found, it is executed. The part after the first space
is taken as arguments, also called parameters. The arguments are
separated by spaces. ZShell will allow up to 25 arguments.

If the commandname was found on disk, it will be analyzed:
 1. If the commandname is a directory, the current directory will be
    changed (see  CD ) to it.
 2. If the script flag is set, it will be  executed  eighter
    as ZShell script or as ARexx script.
 3. If the execute flag is set (and it is set in most cases), it will be
    tried to treat it as normal executable command. 
 4. If the command is not executable, it will be shown using
     amigaguide.library  (This is an easy way to view Guides).

eg.     addbuffers df0: 15
"addbuffers" is the command, that will be found as a internal command.
"df0:" is the first argument. "15" is the second argument. The third
argument does not exist.

You can avoid using an  alias  or an internal (builtin) command or
changing the current directory by typing a point before the
commandname (this is called "force disk").

To abbreviate internal or  resident  commands put a point behind it.
If you use just a point, the current directory will be set to the
last current directory ("dir back").
To get to the parent directory, you have to use a slash ( / ).

eg.     .addbuffers df0: 20
{This uses the disk command or if available the resident addbuffers}
        ad. df0: 20   {uses the internal addbuffers command}
        .add. df0: 20 {if available this uses the resident addbuffers}
        .             {go back to old current dir}

BEWARE of other matching commands! The first matching will be taken!
"as." can mean ASK or ASSIGN, but ASK will be taken !
There is no abbreviation for disk commands, use  Filename  Completion 
( TAB-Key ) instead.

A textual error message will be displayed if an AmigaDOS error occurs.
