It said forty and filled exactly half of an eighty column screen.
CosmOS asks for the wide mode when it starts, because its own help text is
seventy-four characters across. So a program that assumes the shape the
MACHINE wakes up in is wrong about the shape the SYSTEM is running in - and
the Programming Manual says as much where it describes the columns and rows
registers: how big the screen is, is asked for rather than assumed.
Port 0x32 says. One instruction, and the program now fills whatever it is
given.
