random integers betwe en 0 and 99 inclusive.
RUN (RU.)
The RUN statement is used to execute the program that is
currently in the computer's memory . A RUN statement is also
used to load and execute a program from an input device.

RUN ["device:filespec"]
A RUN statement closes the I/ O channels and turns off the
sound voices before executing or loading the program .
When a RUN statement
is used with an input device, the
contents of the computer's memory are erased before the
program is loaded. Only BASIC programs that were recorded
with the SAVE statement can be loaded and executed with a RUN
statement.
The
Program Recorder is activated with a RUN "C:" statement.
The
tone sounds once to remind the operator to position the
tape and press the
Play lever on the Program Recorder followed
by Return on the computer 's keyboard.
A RUN statement can
load and execute a program from a disk file
if the disk operating system has been booted . An error results if
