Files produced during decompilation


 Rescue5 reads and writes information from and to a number of
 different files during decompilation.

 1) Files containing recovered source code

    MAIN.UDF

    Created to contain the first user-defined non init or exit
    procedure encountered.

    LIB.UDF

    Created to contain the procedures below the /s threshold not
    included in a  <procedure>.UDF file (see below).

    <procedure name>.UDF

    Each procedure over the /s threshold is written into a
    separate source file.  Procedures that are interdependent
    through referencing common static variables or procedures are
    grouped together in the same file.

    Duplicate file names are resolved by having an ordinal number
    inserted into the name.

    ORPHAN.UDF

    Unreferenced individual static procedures will be placed in a
    file called ORPHAN.UDF.  ORPHAN files are rare since the
    procedures they contain are "dead" code.

    MODULEnnn.UDF

    A MODULE file is created for each group of interrelated
    static procedures that call each other but are never called
    from anywhere else.  MODULE files are rare since the
    procedures they contain are "dead" code.

    [path\]<original PRG name>.SRC

    Code that was compiled with the CA-Clipper /b switch is
    recovered into file(s) with the same name as the original
    .PRG file, but with a .SRC extension.

    If the original .PRG was compiled in a specific directory,
    Rescue5 will create an equivalent directory for the recovered
    file, using the output directory as root.  Drive names are
    converted to directory names by the drive letter being
    prefaced the word 'drive_'.  Relative paths are resolved to
    absolute.

    For example, assume the .EXE contains the code from two .PRG
    files of the same name but different paths:

       clipper f:\lib\source\myprog.prg /b /n clipper
       g:\lib\source\myprog.prg /b /n

    If these are recovered with the command line:

       rescue myapp.exe /omyapp

    Rescue5 will create:

       c:\rescue5\myapp\drive_f\lib\source\myprog.src
       c:\rescue5\myapp\drive_g\lib\source\myprog.src

 2) Configuration files

    VARIABLE.UDT / <user defined file>

    Variable base name definition files are read by Rescue5 on
    the first pass and are used to create the <EXE name>.VAR
    file for the .EXE being decompiled.

    Variable base name files can be created or modified with a
    text editor.

    <.EXE name>.GRP

    Rescue5 creates a grouping file for the .EXE being
    decompiled during the first pass.  The file can be modified
    with a text editor, and is read by Rescue5 during subsequent
    passes.

    During subsequent passes Rescue5 uses the contents of the
    <EXE name>.GRP file to determine which procedures to write
    into which source files.

    Note that Rescue5 ignores entries for groups that were
    originally compiled with the CA-Clipper /b switch (these are
    always placed in .SRC files with the same name as the
    original .PRG).

    <.EXE name>.VAR

    During the first pass Rescue5 uses the definitions in the
    VARIABLE.UDT file to generate names for local and static
    variables, writing the suggested names into the <.EXE
    name>.VAR file.  The file can be modified with a text
    editor, and is read by Rescue5 during subsequent passes.

    During subsequent passes Rescue5 uses the contents of the
    <EXE name>.VAR file to determine static and local variable
    names, which are written into the recovered source.

    A <.EXE name>.VAR file is not written if all the source code
    in the application was compiled with the CA-Clipper /b
    switch, since Rescue5 recovers local and static variable
    names from the debugger information.


 3) Other files

    ERROR

    If any errors occur during decompilation Rescue5 will write
    them into a file called ERROR.

    <.EXE name>.RMK
    <.EXE name>.LNK

    RMake and linker script files with which to rebuild the
    application.

    REPORT

    The REPORT file lists some overall statistics about the
    application, the states of Rescue5 settings and the contents
    of each of the source modules recovered.
