Do you have access to the C++ source code, or at least the executables? Can you snoop around to see if there are any external libraries referenced by the source or EXE? If you have only the EXE, there are sometimes copyright notices or company names embedded in linked libraries. These might give you a hint as to the identity of the database tools used.

How long ago was the program written? Was it originally written for Windows or VAX? As I recall, a lot of C programmers used to like using libraries called BTree, BTrieve, CTree and the like to program database apps. These libraries are ISAM non-relational libraries usually based on the B-Tree indexing schemes. I vaguely recall seeing ODBC libraries for some B-Tree based databases.

Perhaps if you can identify the library used to access the data you can crack the code. Here is a web page with a partial listing of possibilities: http://www.cbbrowne.com/info/dbmsisam.html

In trying to identify LSR, I came accross various references to databases for the VA (LSR has something to do with length of bed stay) and for Life Sciences Research. Is this by any chance a hospital database? Knowing the purpose might help identify if it relates to a standard for sharing information between agencies.

>I am trying to figure out what the data files origination is, or rather, what will properly open some data I have; this was created by some C++ programmers a while back and no one left int he company with whom I am contracting can figure out what they've got; they only know that it works with the code the guy wrote for them. What a mess. FoxPro for DOS and Windows won't open it. Notepad opens it, but it looks like it too. I haven't tried MS Access yet. Does anyone have any idea what this could be?
