INTRFC - Program to dump TPU files (March, 1994).
Version 7.0:  Dumps TPU, TPP and TPW format files.

INTRODUCTION

Several times I had to write the source of a tpu, because it was
not available. I started to look for some documentation about TPU
files and I found INTRFC from D.J. Murdoch, that works with TP 6.0
tpu files (see history below). Because I needed to dump TPU files
from BP 7.0 and I was wondering how tpu files are encoded, I
upgraded it to BP 7.0 files. I also fixed same mistakes and added
some new features (print enum and set constants etc).

Because D.J. Murdoch does not plan to update INTRFC any more,
please send bugs only to my Internet address.

The reason I included source code is because it will serve as a bit
of documentation for the TPU file format:  Borland will never
publish it.  They want to be free to change the format, tweaking
performance when they can.

You must compile INTRFC in BP 7.0. Normally it will dump only BP
7.0 (TPUQ) files. If you want to dump TP 6.0 (TPU9) files, you must
recompile INTRFC with the symbol UNIT60 defined. Change SWITCHES.INC
or compile with BPC: BPC intrfc.pas /b /DUNIT60


USAGE:
       INTRFC /options unit [output_file]
   where options are letters from the following:
     B - emitted code bytes
     C - initialized constant blocks
     D - code blocks
     E - routine entry records
     G - emitted global const bytes
     H - TPU header
     I - implementation section (if $D was used in compilation)
     L - proc/fn locals (if $L was used in compilation)
     M - source line number map
     N - names in interface
     O - const relocation records
     R - relocation records
     S - source file records
     U - unit list
     V - var blocks
     W - exported name records
     Z - browser section {$Y+}
     A - turn all options on

     Options are processed sequentially and toggle the display.
     Use /Tpath[;path] to set the Turbo directory for TURBO.TPL
      and referenced units.
     E.G. To see all but the relocation records in the system unit,
          use
        INTRFC /AR /T\bp\bin;\bp\units SYSTEM
     The default is just the names in the interface section.

LIMITATIONS

     There are tons of limitations to INTRFC.  It doesn't know how to
     print the values of typed constants. Etc. Etc. Etc. If you want
     it to do something differently just go ahead and change it!

     I recommend compiling with all possible checks turned on, since
     it's pretty easy to get lost in all those pointers and records.

FILES

     The following files should be included in this package.

      INTRFC70 DOC    This file
      TPU9     DOC    TPU structure outline (TP 6.0)
      TPUQ     DOC    TPU structure outline (BP 7.0)
      INTRFC   EXE    The executable to dump BP 7.0 tpu files

      INTRFC   PAS    Main program
      GLOBALS  PAS    Program globals

      HEAD     PAS    TPU header dumper
      NAMELIST PAS    Prints interface section
      NAMETYPE PAS    Type definitions for NAMELIST
      BLOCKS   PAS    Routines for code blocks, etc.
      SRCFILES PAS    Prints source files & line numbers
      RELOC    PAS    Prints relocation records
      CODE     PAS    Code and const dumper

      DUMP     PAS    Various dump routines
      LOADER   PAS    Reads in .TPU and .TPL files
      UTIL     PAS    Various utility routines
      TEST1    PAS    Test file
      TEST1    INC    Test include file
      TEST1    ASM    Test assembler file
      TEST1    OBJ    Test object file
      PARAMS   PAS    Parses parameters

     Have fun with INTRFC and Turbo (or Borland) Pascal.
