if/else/end if

Use the if/else/end if instruction to determine what sections of a script to execute, based on whether a particular Script trigger was received.

Note  The Script Editor automatically creates an else statement for you, though this statement is optional.

Usage:

• Execute a set of instructions if the device receives a Script trigger, execute another set of instructions otherwise:
  
  if scriptTrigger0
      <instructions>
  else
      <instructions>
  end if
• Execute a set of instructions if the device receives a Script trigger:
  
  if scriptTrigger0
      <instructions>
  end if
• Execute a set of instructions if the device has not received a Script trigger:
  
  if scriptTrigger0
  else
      <instructions>
  end if

Note  The if/else/end if instruction must be preceded by a generate or wait <N> instruction. You can nest if/else/end if instructions, but if/else/end if instructions are not allowed in repeat until and repeat <N> instructions.

Examples:

• Generate myWfmB five times if a Script trigger is received, otherwise generate myWfmC:
  
  generate myWfmA
  if scripttrigger0
      repeat 5
          generate myWfmB
      end repeat
  else
      generate myWfmC
  end if
• Generate myWfmA if two Script triggers were received:
  
  wait 8
  if scripttrigger0
      wait 8
      if scripttrigger1
          generate myWfmA
      end if
  end if
• Generate myWfmA if Script trigger 0 was received, or generate myWfmB if Script trigger 1 was received, otherwise generate myWfmC:
  
  wait 8
  if scripttrigger0
      generate myWfmA
  else
      wait 8
  
      if scripttrigger1
          generate myWfmB
      else
          generate myWfmC
      end if
  end if
• If an error is flagged in the form of a Script trigger while generating a waveform, do not generate all subsequent waveforms:
  
  generate myWfmA
  if scripttrigger0
  else
      generate myWfmB
      if scripttrigger0
      else
          generate myWfmC
      end if
  end if
