Execute returns TRUE (-1) if it able to initialize a new CLI process,
regardless of whether that CLI was able to run the specified command(s).
You can watch it fail if you type NEWCLI over and over until you have
20 CLIs in use.  Then your program will return FALSE (0) when it can't
create CLI #21.  

Since the CLI structure is deleted when the Execute()ed programs are done,
I don't think you can get the return value of the last command.

I hope they've added a function to do what you want in 1.4.
