Editing BASIC (section)

==== Input and output ====
; <code>LIST</code> : displays the full source code of the current program.
; {{anchor|PRINT}}<code>PRINT</code> : displays a message on the screen or other output device.
; <code>INPUT</code> : asks the user to enter the value of a variable. The statement may include a prompt message.
; <code>TAB</code> : used with <code>PRINT</code> to set the position where the next character will be shown on the screen or printed on paper. <code>AT</code> is an alternative form.
; <code>SPC</code> : prints out a number of space characters. Similar in concept to <code>TAB</code> but moves by a number of additional spaces from the current column rather than moving to a specified column.
