====== IF ... THEN ... ELSE ======

Syntax:

  if <any relation> [and | or <any relation>] then <statements> [else <statements>]
	
or, since version 2.1:

  if <any relation> [and | or <any relation>] then
    <statements>
  [else
    <statements>]
  endif

Conditional structure. Executes the statements after ''THEN'' if the expression evaluates to true, otherwise the statements after ''ELSE'', if present. ''ELSE'' is optional.

Current limitations:

  * Only one conditional operation (''AND''/''OR'') is supported
  * ''THEN'' may not be omitted

Examples:

	if x >= y/z then print "yes, expression is true"
	if a = b then print "they are equal" else print "they are not equal"
	if a = b or a < 2 then print "they are equal or a is less than two"
	
Please refer to the [[operators|Operators]] page for the list of supported operators.

====== Performance tip ======

An ''ON ... GOTO'' or ''ON ... GOSUB'' construct is faster than its ''IF ... THEN GOTO/GOSUB'' equivalent. Please refer to the [[ON|ON construct]] for details.
