DSP “CO-ORDS + ILO”

Display the title of the
program and pause. DSP
has an automatic
temporary pause before
executing the next line.
01; HLT A,B,C,D,E
HLT halts the program
and sequentially allows
the variables to be
entered. After each

DEG A => A departure latitude
DEG B => B departure longitude
DEG C => C arrival latitude
DEG D => D arrival longitude
DEG E => E intermediate
longitude
These sequences of code
change the degree,
minute and seconds into
decimal degrees for
mathematical
computation. The
resulting answers, if
required, can be
converted back to
degrees, minutes and
seconds. Each variable is
stored in a memory.
There are 26 main
memories available as
well as indirect
memories. The main
memories are A → Z.
Here the memories A →E
are used.
