Basic Tutorial for CoCoA-5
Use the command
ciao;
to get out of CoCoA-5. It is important to type
the semicolon ";" after the word "ciao" -- as a rule, you should put a semicolon
after every CoCoA-5 command. After receiving the
ciao
command, it may
occasionally take a few seconds for CoCoA-5 to fully terminate itself.
If CoCoA is busy computing, it will not heed any further commands
(including
ciao;
) until the computation ends. When CoCoA-5 is ready
for a new command it prints out a prompt; if the previous input was incomplete,
this is indicated in the prompt.
If CoCoA-5 is taking too long with a computation you may "interrupt" it
(i.e. forcibly end it prematurely); it may take a few seconds for
CoCoA-5 to react after you give the interrupt signal. CoCoA-5 will print a
prompt when the computation has been stopped; it is then ready to
receive new commands. The correct way to interrupt a CoCoA computation
depends on the user interface (and operating system).
If you are still stuck inside CoCoA, you can try
*/ciao;
instead;
note the extra two characters "star" and "slash" at the start. You may need
to type this twice.
