Return Values

[jestrada101]

I have a java program that I run and it is to return a -100 value.

After I've run the program, i type "print $?" and expect the -100, but I get 255?

Is there other code executing after the Java program?

If so the printing of the $? will show you the exit code of the last command executed.

I hope this helps.

There is no other code after the java program executes.
Right after it finishes, i type "print $?" and it returns 255 instead of -100, which I'm supposed to get.

Thanks

Capture the return value of your java program, you
are gettig the shell return value which is to be
expected.

Program exit status values are (or were at least) restricted to being small positive integers (0..255).

If you try and return something outside that range, then my guess is that something else happens.

Try returning say +100 instead and see whether that makes it into $? OK.
