Usage Guideline
The help command provides a brief description for the help system, which includes the following functions:
• To list all commands available for a particular command mode, enter a question mark (?) at the
system prompt.
• To obtain a list of commands that begin with a particular character string, enter the abbreviated
command entry immediately followed by a question mark (?). This form of help is called word
help, because it lists only the keywords or arguments that begin with the abbreviation entered.
• To list the keywords and arguments associated with a command, enter a question mark (?) in
place of a keyword or argument on the command line. This form of help is called the command
syntax help, because it lists the keywords or arguments that apply based on the command,
keywords, and arguments already entered.
