Note on the use of the Tutorial with COMPAQ BASIC.

COMPAQ BASIC is contained in two files. The install program copies
only the file BASIC.COM to the program disk. When you run the Tutorial,
COMPAQ DOS will prompt you for the COMPAQ DOS disk so that it can
retrieve the rest of BASIC, contained in the file BASICA.EXE.

You can avoid this extra step by copying the file BASICA.EXE from
your COMPAQ DOS disk to the program disk.
