I was evaluating compilers for the IBM PC in late 1982
or early 1983 and
tried the original Microsoft Fortran. The error message in the manual for
the read sense switch statement was somethine like "you show me the switches
and I will read them."
Games port joystick button inputs, printer status inputs, an input port
mapped into the user area, get the idea? :-)
