Editing BASIC (section)

==== Data manipulation ====
; <code>LET</code> : assigns a value (which may be the result of an [[expression (programming)|expression]]) to a variable. In most dialects of BASIC, <code>LET</code> is optional, and a line with no other identifiable keyword will assume the keyword to be <code>LET</code>.
; <code>DATA</code> : holds a list of values which are assigned sequentially using the READ command.
; <code>READ</code> : reads a value from a <code>DATA</code> statement and assigns it to a variable. An internal pointer keeps track of the last <code>DATA</code> element that was read and moves it one position forward with each <code>READ</code>. Most dialects allow multiple variables as parameters, reading several values in a single operation.
; <code>RESTORE</code> : resets the internal pointer to the first <code>DATA</code> statement, allowing the program to begin <code>READ</code>ing from the first value. Many dialects allow an optional line number or ordinal value to allow the pointer to be reset to a selected location.
; <code>DIM</code> : Sets up an array.
