- Odds are the decompiled code will be so unreadable, it would be
- useless. There is no way to reconstruct the original data structures
- (structs, classes, and unions), and ALL variable name would likely
- contain addresses for names (e.g. i2940). This would render the code
- useless from the start. Someone would spend more time reconstructing
- the code than purchasing the package.
-
- I see no real threat from decompilers. As a VB programmer I have
- tried and tested the decompiler on my own code and it's interpreted.
- The code came back so unreadable, I would spend weeks reconstructing
- the code....

- More importantly, the decompiler must decifer the library code from
- your source code... Imagine, trying to decompile a MS Windows program
- written with OWL or MFC, good luck. Libraries which are linked are no
- different than your compiled code.
-
- Code translators Intel ASM to Motorola ASM are possible and do exists,
- but this does not decompile.
