It is possible to detect if your program is debugged. Debuggers use interrupt 3
for breakpoints. The following example will simply crash the program if its run
with Turbo Debugger, under DOS there's no problem.
CAUTION : this program wil crash if run under a debugger, including the
IDE (when you make use of breakpoints)

Program DebugTest ;
Uses
DOS ;
var
OldInt3 : Pointer ;
{$F+}
Procedure Int3 ; assembler ;
ASM
end ;
Begin
GetIntVec (3, OldInt3) ;
SetIntVec (3, @int3) ;
{ Put breakpoint here }
Writeln ('Breakpoint action ?') ;
SetIntVec (3, OldInt3) ;
end.
