Our very generous guarantee assumes that the following rules are obeyed:


1)  The program to be decompiled was originally compiled without any errors.


2)  The program to be decompiled is identical to the originally compiled program and it has not been mangled by transmission errors, hard-drive corruption, faulty network cards, viruses, or any programs.


3)  When the program is decompiled, the FILELIST.CFG must be functionally identical to the FILELIST.CFG that was used to compile the original program.  This means that datafiles can be added to the FILELIST.CFG and unused datafiles can be removed.  Datafiles that are used by the .FLX program must have the same filelist number both before original compilation and while the .FLX is being decompiled.


4)  The .FD files supplied when the program is recompiled must be functionally identical to the .FD files that were used to compile the original program.  This means that field definitions much be identical between the original .FD and the current .FD.  New fields can be added to the end of a datafile definition without affecting decompiling.


5)  When the program is recompiled, an unmodified FLEX.CFL (as provided by Data Access Corporation) is used. 


The .TAG files used for decompiling do not have to be identical to the original .TAG files that were used to compile the program. They must, however, match the .FD file(s) that are used for recompiling.  The name of a field is only a cosmetic issue.  Calling a field Customer.Address or Customer.Addr or Customer.Field_3 does not affect the decompiler as long as the .FD file calls the same field Customer.Address, Customer.Addr or Customer.Field_3.

The DataFlex Decompilers target the source code for the same version of DataFlex as the .FLX file.  Recompiling a source file under a different version of DataFlex may require programmer induced changes, just like the original sources would have had to be modified.

The DataFlex decompilers can usually generate some kind of code even when some of the rules are not valid.  The generated code may use generic filenames or field names.  In the case of #5, the FLEX.CFL can contain new custom macros that were not provided by Data Access Corporation without affecting how the recompiled program behaves.

If you have specific questions about the quality of a program's code  when you can't follow all of the rules in the disclaimer, then please see our Decompiler FAQ or contact us by emailing to get an answer.
