Allow me to clarify other's responses.
When you build your program in the NXT-G software,
you are making a "source" program that includes the icons, their arrangement on
the grid, their values, comments and all the other parts of what you think of as
your program.
When you download it to the NXT, the NXT-G software
"compiles" your source program into something known as "object code". This
is a rewriting of your program into thousands of little instructions telling the
hardware what to do. If you use another NXT software program, such as
Robo-C, the source code will look wildly different even if the object code does
the same operations.
While the NXT allows you to upload a program from
the brick back onto your computer, this is only the object code. The
object code can be downloaded onto any brick and it will run just fine,
but you cannot "decompile" the object code to recreate your source
program.
This is why any experienced coach will
recommend that all programs be backed up after all practices. We usually
just copy them onto a thumb drive into a separate directory named for the date
of the practice. This also lets you recover programs that were
accidentally deleted.
Sorry for the bad news but hopefully others will
have learned from this email thread.

My students lost a program from the computer, but still have it on the

further work. Can anyone help?
