Notation

The description of a command begins with the command name in the upper left corner, followed by the syntax of the command. In the same line there is the minimal abbreviation of the command on the right.

If there are other commands with the identical syntax and the same meaning as the command to be explained, the other commands are listed behind the first command and separated with a vertical line (`|`). Example:

BACK|UP|-      [n]
BA|U|-

To describe the parameters (or operands) of a command, the following notation is used:

square brackets ([ ]):

They occur before and behind parameters which may be either specified or left out. In the latter case a default setting takes place, which is precisely described.
Example: BACK [n] means that you may either use `BACK' or `BACK n'. In this case, the default setting is 1. For more information, compare the description of the command BACK.

vertical line (|):

This character separates equivalent parameters, of which you must not specify more than one.
Example: SKEY [n|?] means that you may enter either `SKEY n' or `SKEY ?' (or only `SKEY') but not `SKEY n ?'. You find more details in the explanation on the command SKEY.

small letters:

Small letters are used for parameters, for which you have to set (numerical) values.
Example: UP [n] specifies by how many records the current line has to be moved upward. To use this specification you have to use a number for n (if you specify a parameter).

capital letters:

Capital letters are used for parameters you have to use precisely the way they are described. Of course, you may write them in small letters to enter them. The distinction in this text only serves to convey the information whether or not you have to replace a parameter word with a value.

Please, keep in mind that parameters may be abbreviated as well if the abbreviation is not ambiguous. The minimal abbreviation of parameters is not explained in this text.
