SAC Command Reference Manual

HELP

SUMMARY

Displays information about SAC commands and features on the screen.

SYNTAX

HELP {item ...}

INPUT

item:The (full or abbreviated) name of a command, module, subprocess, feature, etc.

DEFAULT VALUES

If no item is requested, an introductory help package is displayed.

DESCRIPTION

Each requested item in the help package is displayed in the order they are requested. A short message is displayed if no information is available for an item. After a full page of output, the user is prompted to see if he or she wishes to see more information on that item. A response of "NO" or "N" will terminate the display of that item and will begin the display of the next item if any. A response of "QUIT" or "Q" will terminate the display of all items. The help package for each command consists of the entry in the SAC Command Reference Manual. The help package for non-commands may be paragraphs from the SAC Users Manual or other information.

EXAMPLES

To get the introductory help package type:

SAC> HELP

Now lets say you want information on several commands:

SAC> HELP READ CUT BEGINDEVICE PLOT

SAC begins displaying the READ help package. After a full page, it asks if you've seen enough:

   MORE?
SAC> YES

SAC displays the rest of the help package on READ, and then begins displaying the help package on the CUT command:

   MORE?
SAC> NO

SAC stops displaying the CUT help package and begins displaying the BEGINDEVICE help package:

   MORE?
SAC> QUIT

You're getting impatient so you type QUIT. SAC terminates the HELP command so you can try some of the features discussed.

ERROR MESSAGES

  • 1103: No help package is available.
    • SAC can't find the help package. Check your SACAUX environment.
