I *almost* had that figured out.  I see that the ">" and "<" operators 
apply to opening *files* whereas the *pipe* can be used with values and 
commands.  I was getting ready to try it with a "1" instead of "0" for the 
file descriptor.  That obviously does not work since the pipe is taking 
stdout and piping it to stdin of the next command.  stdin of the gpg 
command segment is file descriptor 0 instead of 1.

Thanks for setting me straight!
