CoCoA's online help is roughly divided into two parts: a manual and a
list of commands. The manual includes a tutorial which can be started
If you are a new user of CoCoA, the tutorial is a good place to start.
To see the titles of the sections of the online manual, enter
; to see a list of commands, enter H.Commands("")
Each section of the manual and each command is uniquely identified by
a set of keywords. The set of keywords always includes the title of
the section or the title of the command. The online help command ?
takes a string from the user and searches for a match among the
keywords. For instance, ?gbasis
will display information
about the function
. Note that when using ?
, the keyword
does not appear in quotes. Also, a semicolon is not required.
The command ??
will return a list of entries in the manual that
contain a given keyword. For instance, ??gbasis
Each command is associated with a list of topics. (This applies only
to commands, not to sections of the manual.) The online help function
takes a string from the user and searches for all matches
among these topics. For each match, the title of the command and a
brief description is displayed. For instance, H.Commands("poly")
will find all commands having to do with polynomials. Information
about a specific command can then be retrieved with ?
. A list of
topics is provided by H.Commands()
, with no argument.
IMPORTANT NOTE: Searches are case insensitive and your keyword need
only be a substring to make a match.
For a thorough description of the search function ?
, type ? ?
a space between the two questions marks.
