Usage
Use to set a customized message on a user-defined exception object. Although it is possible to use SetMessage to modify the preset error messages for RuntimeError objects, this is not recommended.
Examples
This statement is an example of a message set on a user object of type Throwable:
MyException.SetMessage ("MyException thrown")This example uses SetMessage in the try-catch block for a user-defined function that takes an input value from one text box and outputs the arccosine for that value into another text box:
uo_exception lu_error
Double ld_num
ld_num = Double (sle_1.text)
TRY
sle_2.text = string (acos (ld_num))
CATCH (runtimeerror er)
lu_error = Create uo_exception
lu_error.SetMessage("Value must be between -1" +&
"and 1")
Throw lu_error
