s worth of text or has completed displaying
the previously requested help. The information displayed by SCUHELP on a particular
topic includes a description of the topic and a list of subtopics that further describe the
topic.
At a prompt you may enter:
a topic and/or subtopic name(s) to display the help for that topic or subtopic, so for example, "
block
parameters box"
gives help on BOX, which is a subtopic of Parameters, which in turn is a subtopic of
BLOCK;
a CR
to see more text at a "
Press RETURN to continue ..."
request;
a CR at topic and subtopic prompts to move up one level in the hierarchy, and if you are at the top level it will terminate the help session;
a CTRL/D (pressing the CTRL and D keys simultaneously) in response to any prompt will terminate the help session;
a question mark "
?"
to redisplay the text for the current topic, including the list of topic or subtopic
names; or
an ellipsis "
..."
to display all the text below the current point in the hierarchy. For example,
"
BLOCK..."
displays information on the BLOCK topic as well as information on all the subtopics
under BLOCK.
You can abbreviate any topic or subtopic using the following rules.
Just give the first few characters, e.g. "
PARA"
for Parameters.
Some topics are composed of several words separated by underscores. Each word of the keyword may
be abbreviated, e.g. "
Colour_Set"
can be shortened to "
C_S"
.
The characters "
%"
and "
"
act as wildcards, where the percent sign matches any single character, and asterisk matches any
sequence of characters. Thus to display information on all available topics, type an asterisk in reply to
a prompt.
If a word contains, but does end with an asterisk wildcard, it must not be truncated.
The entered string must not contain leading or embedded spaces.
Ambiguous abbreviations result in all matches being displayed.
