The common BASIC dialect on home computers of the 1970s and 1980s is Microsoft
BASIC 4.7 or very similar. Generally speaking, the dialect supports a single
user-defined FCN()
which allows for a user defined expression with a single
input parameter. Occasionally it will support machine-code methods with USR()
.
