A: Borland's separate 
Turbo Profiler is a powerful tool for
improving program code and enhancing program performance, 
but far
from an easy to use. It is an advanced tool. In fact setting it up
the first time is almost a kind of detective work.
   Let's walk through the steps with Turbo Profiler version 1.01 to
see where a running Turbo Pascal program takes its time.
Assume a working directory r:\
1. Copy the target .PAS file to r:\
2. Compile it with TURBO.EXE using the following Compiler and
   Debugger options. The standalone debugging option is crucial.
     Code generation
      [ ] Force far calls        [X] Word align data
      [ ] Overlays allowed       [ ] 286 instructions
     Runtime errors             Syntax options
      [ ] Range checking         [X] Strict var-strings
      [X] Stack checking         [ ] Complete boolean eval
      [ ] I/O checking           [X] Extended syntax
      [ ] Overflow checking      [ ] Typed @ operator
                                 [ ] Open parameters
     Debugging
      [X] Debug information     Numeric processing
      [X] Local symbols          [ ] 8087/80287
                                 [ ] Emulation
     Debugging         Display swapping
      [X] Integrated    ( ) None
      [X] Standalone    () Smart
                        ( ) Always
3) Call TPROF.EXE
4) Load the .EXE file produced by compilation in item 2.
5) Choose from the TPROF menus

Also see Edward Mitchell (1993), Borland Pascal Developer's 
Guide.
It has a a very instructive chapter "Program 
Optimization" on the
Turbo Profiler. The material in the Turbo Profiler manual is so
complicated that additional guidance like Mitchell's is very much
needed.
