ObjectPAL Exception Trapping

ObjectPAL has a try...onFail statement but does not have a finally-type component. However, the code afer endTry will execute.

try

onFail

endTry

Here is an example from a pushButton event:

method pushButton(var eventInfo Event)
var
 i SmallInt
endVar

errorTrapOnWarnings(True)

try
  i = 0
  i = 1/i
  msgInfo("", "This line of code never executes.")
onFail
  msgInfo("", "You cannot divide by zero.")
endTry

msgInfo("", "This line always executes.")
endMethod

The following example shows you the last ObjectPAL error:

errorTrapOnWarnings(yes)

try

  ;Your code here

onFail

  msgStop( errorCode(), errorMessage() )

  ;You could also use errorShow()

endTry
