The files ../8_* have been copied here and then renamed.
First give the command

   make

The make command accomplishes the following:

   1  creates the executable file (program) try_me

   2  uses chmod to make the shell script go_try executable

Next, give the command

   try_me

so that you understand its effects.  Finally, give the command

   go_try

Input a variety of integers, including -1, to see the status
being returned to the operating system by the program try_me.
