The Reader is Warned!

The pages which follow have been lifted more or less verbatim from the documentation for the Unix-based implementation. The vast majority of this code should work as advertised, but it is very likely that there will be some operating-system dependencies which will need to be weeded out eventually.

Please note that the {domino} symbol is mapped in the KAPL font to the character which is treated by modern web-browsers as the 'optional hyphen'. This means that dominos only appear when they occur at the end of lines. Experienced APLers might like to compute the probability of this ever happening! If you really want to see them, use Netscape 4 or earlier to view these pages.
