DEFINITION
Graphic block-type diagram used to describe
d i f f e r e n t o p e r a t i o n s a n d c a l c u l a t i o ns
performed by program and flow (order of
occurrence) of program execution.
Frequency Modulated.
Mathematical reference point on earth which
coincides with MSL and perpendicular to
f o r c e o f g r a v i t y .
Algebraic sum of geoid height and elevation.
Greenwich Mean Time.
Combining of two different frequencies to
produce an intermediate frequency.
Produces transfer of memory address. When
called, it points to address of memory

denotes one of nine rows of keys (from top
to bottom) .
Second digit denotes which of
