function is used to search the online help system for
information matching a keyword.
In the forms ?key
, the key
is a literal string.
This means that key
should not appear enclosed in quotes.
For instance, ?gbasis
is equivalent to Man("gbasis");
The command ?
is case insensitive and does not notice blank
space before or after key
. Also, the semicolon usually
required at the end of a line of CoCoA input is optional.
was introduced in CoCoA 4.2)
The online help contains a manual and a list of commands. Each
section of the manual and each command has an associated list of
keywords. To explain how the search system works, we will use the
following terminology: say the key S matches
a keyword K if S is a
substring of K, not counting capitalization. The key S is an exact
if it is identical to K, not counting capitalization. The
searches for keywords in the online help system matching
the S. If only one match occurs or an exact match occurs, the
corresponding information is displayed. Otherwise, if more than one
match occurs (and no exact match), matching keywords are listed. It
is often advisable to make search words small at first to get as many
matches as possible.

Intelligent choice of the string S can save a lot of typing. For
example, there are many sections in the manual whose titles begin:

corresponding section for polynomials by choosing the search string
The command ??S
displays all keywords in the online help system that
match S (an exact match is not required, and all
keywords are listed
even if there is an exact match).

entry for GBasis
The function Man
is equivalent to ?
except it requires an actual
string, e.g., Man("gbasis")
rather than Man(gbasis)
with the optional second argument set to the number 0 is equivalent to
. Since Man
requires more typing than ?
, there should never
be a need to use it.
Note: The set of keywords associated with any section of the manual
always includes the title of the manual, so it might help to first
take a look at the table of contents, using H.Toc
(The titles of Parts, which are numbered by H.Toc
appear as keywords: only titles of chapters and
Similarly, the set of keywords for a command always includes the
command's name. The complete list of documented commands can be
printed by entering H.Commands("")
