Re: [U2] srs4uv.com status [Was: Corrupted object in global catalog]
You are spot on Ian. It was a fun and tedious exercise. And you are right. The internals of each interpreter and its op codes are quite different. I wanted to answer the same question of how does one thing turn into another. And, can I reverse that? history The first decompiler was for Prime INFORMATION in 1982. There wasn't documentation available to me per se. However, looking through their compiled libraries you could glean the names of the op codes. Returning the statements and functions was straight forward. Recovering the logical structure of the program was the heavy lift. Way back then, what discussions I could find on logical structure recovery all said it was impossible. I discovered a way to take the distinct graph patterns associated with each compiled structure and reconstruct the original structure. That was a fun puzzle. Still today, most decompilers only return GOTO-filled source code. I always insisted on no-GOTOs (unless the original code was a pile of spaghetti originally) and there was no other way to reconstruct the program. The UniVerse decompiler came out in 1992. VMark was nice enough to leave a lot of useful information in some C language header files distributed with the product. I briefly looked at doing a UniData decompiler and never found sufficient time to dedicate to cracking that. Lee Leitner had a UniData decompiler on the market for a while. /history -Original Message- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of McGowan, Ian Sent: Friday, January 04, 2013 8:00 PM To: U2 Users List Subject: Re: [U2] srs4uv.com status [Was: Corrupted object in global catalog] Seems like a fun, if tedious, exercise in understanding the internals of compiled code.

This was a commercial product that was at one time successful. And I am guessing here is no longer used much for whatever reason, hence the need for donations to keep the site going. Most of the time I have seen recovery it is because a programmer left the company or changed a program and deleted the source code by accident. That is why I cannot live without version control. I just go back a version or two to get the working source using our Eclipse based editor and Subversion. No more BP.OLD, no more MyProgram.01-12-2012, no more other archive directories, and no more pulling source off of a QA or test machine. One time, a digression, I had get the source code off a customer machine to get a working copy. Oh boy am I glad those days are behind me. And to those companies that are not shipping source to your customers, those customers better have a stable third party that is saving off the source code for them in case of emergencies.
