Input locations altered:
*** 65 BULK LOAD ***
FUNCTION
Instruction 65 inputs given values in up to eight
Input Storage locations.
The Bulk Load instruction has 9 parameters.
The first eight are the values to be entered in
input storage locations. The ninth is the input
location for the first data value; subsequent data
values are placed in sequential input locations.

*** 66 ARCTAN ***
FUNCTION
Calculate the angle in degrees whose tangent is
X/Y. The polarity of X and Y must be known to
determine the quadrant of the angle, as shown
here. If 0 is entered for Parameter 2, the
Arctangent of X is the result (limits of
ARCTAN(X) are -90 < ARCTAN < 90 ).
