SECTION 11.

OUTPUT PROCESSING

INSTRUCTIONS

(defined

as the

bin

select

value)

is within

particular

subrange

the

total

specified

range.

The count in

the

bin associated with

each

subrange is incremented

whenever

the value

falls within

that

subrange. The value

which

output to Final

Storage

for each

bin is

computed

by dividing the

accumulated total

in each

bin by

the

total number

of scans: This form

of output

also

referred

as a frequency distribution.

The weighted

value

histogram

uses data lrom 2

input locations.

One location contains

the bin

select value;

the other

contains the weighted

value. Each

time

the instruction is

executed,

the

weighted value

added to a bin. The

sub-

range

that

the bin select value is in

determines

the bin to which

the weighted value

added.

When the

Output Flag is set, the

value

accumulated in

each bin

divided

by the

TOTAL number

of input

scans to obtain

the

values

that are

output to Final Storage.

These

values are

the contributions of

the sub-ranges to

the overallweighted

value.

obtain

the

average of the weighted values

that occurred

while the

bin select value was within

pafiicular

sub-range, the value

output to

Final

Storage

must

divided

by the fraction of time

that the

bin select

value

was

within

that

particular

sub-

range

(i.e.,

a standard

histogram of the

bin

select

value

must also

output).

For

either histogram,

the

user

must

specify: 1)

the number of repetitions, 2) the number

bins, 3) a form

code

specifying

whether

closed or open form

histogram is desired

(see

below), 4)

the bin select

value

input

location, 5)

the weighted value

input location

(see

below),

the

lower range

limit, 7) the

upper range

limit.

The

standard histogram

(frequency

distribution)

specified

entering

"O"

in the weighted

value

input location

parameter.

Otherwise,

this

parameter

specifies

the input location

of the

weighted value.

With more than

one repetition

the bin select value

location

will

be incremented

each repetition

and

the weighted value location

will remain

the same

(same

weighted

value

sorted on the

basis of

different bin select

values). The weighted

value

location

will

incremented

entered as an indexed

histogram may be

open form includes

all

values

excludes any values
