Exceptions
"To catch an exception by its name you will need to include sysUtils in every unit that may throw an exception"
That makes no sense whatsoever.
unit divzero;
interface
procedure DoDivByZero;
implementation
procedure DoDivByZero;
var
A, B: Integer;
begin
A := 1;
B := 0;
A := A div B;
end;
end.
This unit does NOT include sysutils.
If you call it from the main program, and your main program uses SysUtils, then you can catch the exception by name: "EDivByZero: Division by zero". --Bart (talk) 13:47, 23 January 2021 (CET)
