General
For any remotely-operated system, the provision of up-to-date information about the
performance of the system is of major importance. In the case of systems which operate
under automatic control, the controller requires the necessary feedback to enable it to
progress the task; any break in the continuity of the process can have serious results.
When developing an application program, the programmer needs to test and revise it,
knowing its effects. Confidence that the program elements are couched in the correct
grammar and syntax (and that the program commands and queries are thus being accepted
and acted upon), helps to reduce the number of iterations needed to confirm and develop
the viability of the whole program. So any assistance which can be given in closing the
information loop must benefit both program compilation and subsequent use.
Such information is given in the following pages.
