udcname
Any existing UDC. To display all UDCs within a UDC file, specify the

commandname
Any MPE/iX command. MPE/iX displays the command name and syntax.
In addition, a list of keywords for that command is displayed.
The HELP command also provides help on UDCs, command files, or
program files. The search order is UDCs, built-in commands (MPE/iX),
command files, and then program files. The search order for UDC's is user
level, account level, and system level. The search order for command files
and program files is determined by the contents of the CI variable HPPATH.
If the user's HPPATH does not contain the name of the current group, the
user can print a command file from the current group, but cannot get help
information.
For UDCs and command files, help displays the text of the user command,
unless the file contains the NOHELP option. In those cases, the display is
suppressed. In the case of program files, help displays a header identifying
it as a program file and the fully qualified file name of the program file.
