*** 78 SET HIGH OR LOW RESOLUTION ***
DATA STORAGE FORMAT
FUNCTION
This instruction enables high resolution (5
character) or low resolution (4 character) final
data storage format. Instruction 78 should be
entered ahead of the output instructions for
which the specified resolution is desired. The
default format is low resolution. At the
beginning of each program table execution, the
low resolution format is automatically enabled.

Outputs Generated:
*** 79 SAMPLE ON MAXIMUM OR ***
MINIMUM
FUNCTION
Instruction 79 samples specified input location
values at the time a new maximum or minimum
value is detected by a previous Maximize (73)
or Minimize (74) Instruction. When the Output
Flag is set, the values copied to Intermediate
Storage are transferred to Final Storage.
Instruction 79 must directly follow the maximum
or minimum Instruction to which it refers. If the
previous Instruction 73 or 74 has more than 1
repetition, Instruction 79 samples whenever a
new maximum or minimum is detected in any of
the locations. If sampling is to occur only when
a specific input location shows a new maximum
or minimum, the previous Maximize or Minimize
Instruction should have one rep referring to that
input location.

Outputs Generated:
*** 80 SET ACTIVE STORAGE AREA ***
FUNCTION
Instruction 80 is used to redirect Output data to
either of the Final Storage areas or to Input
Storage and to set the array ID for Final
Storage. At the beginning of each table the
Active Output area is set to Final Storage Area
1.
When directed to Final Storage, the second
parameter can be used to set the output array
ID. Instruction 80 should follow the instruction
setting flag 0. If parameter 2 is 0, the array ID
is determined by the instruction location
number of Instruction 80 or by the instruction
that set the Output Flag, whichever comes last.
When data are sent to Input Storage, no array
ID is sent.

*** 82 STANDARD DEVIATION IN TIME ***
FUNCTION
Calculate the standard deviation (STD DEV) of
a given input location. The standard deviation
is calculated using the formula:

S = ((ΣX - (ΣX

where X is the ith measurement and N is the
i
number of samples.
