Tutorial-1 for CoCoA-5
CoCoA-5 includes an on-line manual which explains what the various
commands and functions do. To consult the manual you use
?
followed by a keyword; for instance to find out how to compute
GCDs in CoCoA, you could type
?gcd
. This will print out the
corresponding manual page. Notice at the bottom that there is usually
a list of related manual pages (with
?
at the start so you can
easily cut-and-paste to go to the indicated manual page).
If your keyword does not identify a unique manual page then you will see
a list of manual entries which do contain the keyword; again each entry
is preceded by
?
to make it quicker to use cut-and-paste.
A double-query will simply list the titles of all manual pages containing
the keyword: for example try
??gcd
.
Unlike for normal commands, there is no need to type a semicolon at
the end of a manual query (but you can type one if you want).
