if <expression> then <command>

If the specified expressions returns TRUE, then the command after "then" is executed, otherwise the script continues with the next line.

<expression> can have the following format:

•	Operand1 <= Operand2

•	Operand1 < Operand2

•	Operand1 <> Operand2

•	Operand1 = Operand2

•	Operand1 > Operand2

•	Operand1 >= Operand2

Operand1 and Operand2 can be numbers, strings, variables or the result of a built-in function.

Example 1:

Jump to the label "noUpdate" when no updated bookmarks are available.

$updated = GetUpdatedBookmarkCount
if $updated=0 then goto noUpdate

Example 2:

Display a question box and perform different actions, dependent from the button that has been clicked.

QuestionBox "Click yes or no"
if GetQuestionBoxResult="yes" then goto yes_has_been_clicked
if GetQuestionBoxResult="no" then goto no_has_been_clicked

label yes_has_been_clicked
  // insert commands here
  goto continue

label no_has_been_clicked
  // insert commands here

label continue

Example 3:

Loop with 10 iterations.

$i=1
Label BeginLoop1
  if $i > 10 then goto EndLoop1

  // commands, for example a Messagebox which displays the iteration number
  MessageBox "Iteration #: {$i}"

  $i = $i + 1
  goto BeginLoop1
Label EndLoop1
