This time nothing happens externally except that the program appears in the upper part of the screen
This means that it is accepted as correct grammar or syntax. It conforms to the rules of SuperBASIC,
but it has not yet been executed, merely stored. To make it work, type:
RUN
The distinction between direct commands for immediate action and a stored sequence of instructions
is discussed in the next chapter. For the present you can experiment with the above ideas and two
more:
LIST
causes an internally stored program to be displayed (listed) on the screen or elsewhere.
NEW
causes an internally stored program to be deleted so that you can type in a NEW one.
