?HELP Command
?HELP Command
The ?HELP command displays information about the syntax of the Enform Plus
language. The command can also display information about user-defined topics if your
system manager has provided this information. The syntax of the ?HELP command is:
help-element
is a topic for which help is available. Among these topics is the syntax of the
Enform Plus statements, clauses, commands, and language elements. To obtain a
current list of the help-elements, enter the ?HELP command without help-
element. Enform Plus responds by displaying a list of all the topics for which help
is available.
When specifying the ?HELP command, enter help-element in either upper or lower case
characters. Enform Plus accepts unambiguous abbreviations for help-element. If
you use an ambiguous abbreviation, Enform Plus displays help text for all help-
elements beginning with those characters.
A help-element might be an Enform Plus keyword (for example, LIST). If help-
element is an Enform Plus keyword, Enform Plus displays the syntax of the
statement, clause, command, or language element associated with that keyword.
Alternatively, a help-element might be a category of Enform Plus keyword (for
example, report format). If help-element is a category, Enform Plus displays the
syntax for all Enform Plus keywords in that category.
Enform Plus retrieves the text of help messages from the Enform Plus message table. By
modifying the message table, you can modify the help text. See the Enform User's
Guide for information about modifying the message table.
The following example shows a list of topics that might be displayed when you enter the
?HELP command without help-element:
