TRIGG

ER

SETTING*

3 7

8

+

*To

determine

when

to

insert

the

fill

character

in

the

Edit

Mask,

the

hardware

employs

a

Significance

Trigger.

This

trigger

is

set

to

zero

initially.

The

zero

setting

specifies

the

fill

character

in

the

edit

mask

positions.

The

trigger

retains

a

zero

setting

until

either:

1.

A

Digit

Select

character

in

the

mask

references

the

first

non-zero

numeric

digit

in

the

packed

(sending)

field,

2.

OR

A

Significance

Start

character

has

been

encoun-

tered

in

the

Edit

Mask

field.

The

trigger

is

set

to

1

after

either

of

these

conditions.

The

1

setting

specifies

insertion

of

the

digit

(regard-

less

of

value)

from

the

packed

field

in

the

Edit

Mask

where

a

Digit

Select

character

is

present.

The

1

set-

ting

also

specifies

insertion

of

editing

symbols

pres-

ent

in

the

Edit

Mask.

The

setting

of

1

is

retained

until

either

a

plus

sign

is

encountered

in

the

packed

field

or

a

field

separator

character

is

encountered

in

the

Edit

Mask.

Either

of

these

conditions

resets

the

trigger

to

zero.

The

Edit

instruction

sets

the

Condition

Code

to

zero

ifthe

packed

field

has

a

zero

value,

to

one

if

the

value

is

negative,

and

to

two

if

the

value

is

positive.
