Question

I have a server program, it receipt the tcp data package,then process,then return the result with tcp package.
the data come from the sap system.

, but I am not sure what that really means, either.

By default, LV converts all of the datatypes to be in big endian form.
I'm not sure about your SGI, but if it is a little endian machine, then
that will cause problems. If that is the case, you will want to swap
the words and bytes of the four byte values.
To debug this more easily, you might just make sure you send over very
predictable data such as 0, 1, 2, 3, etc. Lots of times these are
tested with random data, but that makes it pretty hard to see a pattern
when the data is wrong.
