CLI conventions
Command line interface (CLI) documentation conventions are as follows:
italic—Used for variables in commands and parameters, for example: DISPLAY ccuu
underline—Underline indicates the default value, for example: YES|NO
< >—Angle brackets enclose variables or explanatory text when it includes multiple words, for example: <list of
device numbers>
[ ]—Square brackets enclose optional values, for example: DISPLAY [DETAIL]
|—A vertical bar indicates alternate selections (the bar means “or”), for example: RUN|NORUN
{ }—Braces are used together with the vertical bar (|) to indicate the start and end of alternate selections, for example:
{DEV symdv#|CUU ccuu}
...—An ellipsis indicates nonessential information omitted from the command output example.
Keywords appear in uppercase (for example, ALL). They must be spelled exactly as shown.
For easy reference, command keywords can be supplemented by lowercase letters to form a meaningful word (for
example, CoNTROLler). When typing a command, use only CAPITALIZED characters of any keyword.
Aside from the characters listed above, you must type all other characters that are shown in the syntax statements.
