This is off the subject, but how do typical Ada compilers (or GNAT if
specificity is required) handle the above list of I/O statements?  I'm
thinking back to my FORTRAN days when I would typically use a single FORTRAN
WRITE/FORMAT statement combination to print out entire escape sequences with
"one" command.  Does the Ada compiler aggregate the above statements into one
buffer for issuance to the serial port or the ANSI driver?  Or does it
literally send seven separate I/O commands?  And what, if any, execution
efficiency is lost if the latter is true?
