# Test Machine interface (MI) operations 
# Verify that, using the MI, we can run a simple program and perform
# exec-step-instruction and exec-next-instruction.  

# The goal is not to
# test gdb functionality, which is done by other tests, but to verify
# the correct output response to MI operations.
