-<TODO>
+The {\ttfamily NEXT} statement is used as part of a for-loop in BASIC.  Each
+use of the {\ttfamily FOR} statement will need a corresponding {\ttfamily NEXT}
+statement, and {\ttfamily NEXT} will never be used without {\ttfamily FOR}.
+When a program reaches the {\ttfamily NEXT} statement, the program goes back to
+the corresponding {\ttfamily FOR} statement and evaluates whether it needs to
+re-enter the loop or not.\\
+
+A {\ttfamily NEXT} statement can take no arguments, or it can take many
+arguments specified as a comma-separated listed.  These arguments must be loop
+counter variables that were created by by {\ttfamily FOR} loops.   When no
+arguments are supplied, the {\ttfamily NEXT} statement will return control to
+the last {\ttfamily FOR} statement that was started.  If loop counter arguments
+are supplied, the {\ttfamily NEXT} statement will will evaluate the variables
+from left to right, completing the first loop counter's for-loop before jumping
+to the next.\\
