While reading the tutorial it is highly recommended that you have
a copy of CoCoA running in a separate window in order to play with the
If you are using the CoCoA GUI (Graphical User Interface) then you
should follow the dedicated link Graphical User Interface
To execute a CoCoA command, type it into the window, ending it with a
semicolon, then press the return
key or enter
key (depending on
your system). A command can run over several lines; CoCoA will wait
for a semicolon before processing the command. Also, several commands
may be written on a single line (each ending with a semicolon).
See the next section for examples.
IMPORTANT NOTES for Macintosh OS 9 (up to version 4.0):
1. Only the enter
key (on the far right of the keyboard is the one
to use) will function to enter CoCoA commands. Experiment.
2. To enter multiple lines, one needs to highlight the lines using the
mouse before hitting the enter
key. Otherwise, the enter key just
feeds the line containing the cursor to CoCoA.
