 +====== FOR ... NEXT ======
  
 +Syntax:
 +
 + for <byte or int variable>​ = <byte or int expression1>​ to <byte or int expression2>​
 + [statements...]
 + next <​variable>​
 +
 +The ''​FOR ... NEXT''​ construct will assign the result of ''​expression1''​ to the given variable, then iterate the variable until it reaches the value of  ''​expression2'',​ executing the commands between ''​FOR''​ and ''​NEXT'' ​ as many times as necessary. ''​FOR ... NEXT''​ constructs can be nested.
 +
 +**Note #1**: the value of ''​expression2''​ is evaluated only once, before starting the loop.
 +
 +**Note #2**: it is not possible to omit the variable name after the ''​NEXT''​ statement.
 +
 +**Note #3**: the runtime library will not check the consistency of your ''​FOR ... NEXT''​ blocks. If there is a ''​NEXT''​ without ''​FOR'',​ for example, the program will likely break.
