This code in the Clicked event of a button catches
a runtime error that occurs when an arccosine is taken for a user-entered
value—passed in a variable—that is outside of
the permitted range:

1	Double ld_num

1	ld_num = Double (sle_1.text)

TRY

1	sle_2.text = string (acos (ld_num))

1	CATCH (runtimeerror er)

1	MessageBox("Runtime Error", er.getmessage())

END TRY
