When a PICTURE clause is specified with a USAGE clause, the specifications must be compatible.
COMPUTATIONAL Option
A COMPUTATIONAL data item has a decimal numeric v a l u e . T h e P I C T U R E p i c t u r e - s p e c i fi c a t i o n c a n c o n t a i n t h e c h a r a c t e r s 9 ( d i g i t p o s i t i o n ) , S ( o p e r a t i o n a l s i g n ) , V ( i m p l i e d d e c i m a l p o i n t ) , a n d P ( a s s u m e d d e c i m a l s c a l i n g p o s i t i o n ) ; e d i t i n g characters can also be included.
COMPUTATIONAL-1 Option
The COMPUTATIONAL-1 format describes a fixed-point I n t e g e r , w h i c h i s r e p r e s e n t e d i n t e r n a l l y a s a 4 8 - b i t b i n a r y i n t e g e r, r i g h t - a l i g n e d i n t h e w o r d . A corresponding PICTURE clause must be numeric and c a n i n c l u d e e d i t i n g c h a r a c t e r s . I f a P I C T U R E
clause is not specified, the default is PIC 9.
COMPUTATIONAL-2 Option
A COMPUTATIONAL-2 data item is stored as a normal i z e d fl o a t i n g - p o i n t b i n a r y r e p r e s e n t a t i o n o f a
INDEX Option
The USAGE IS INDEX clause specifies a data item t h a t i s u s e d w i t h i n d e x e d t a b l e s . T h e i n d e x d a t a i t e m c o n t a i n s a v a l u e t h a t m u s t c o r r e s p o n d t o a n occurrence number of a table element. The INDEX option Is not used by CDCS; it can be included in t h e s u b s c h e m a d e s c r i p t i o n f o r u s e b y t h e Q u e r y Update application program.
A n i n d e x d a t a i t e m i s a n e l e m e n t a r y i t e m , o n e computer word in length, and binary in format. Its m o d e c o r r e s p o n d s t o a n i t e m d e s c r i b e d a s COMPUTATIONAL-1; the item must be numeric and must not exceed 18 digits.
The SYNCHRONIZED, JUSTIFIED, and PICTURE clauses cannot be used to describe a group or elementary item that specifies USAGE IS INDEX.
DOUBLE Option
A D O U B L E d a t a i t e m i s s t o r e d a s a n o r m a l i z e d fl o a t i n g - p o i n t n u m b e r t h a t o c c u p i e s t w o c o m p u t e r words. The data item can be 29 digits.
A corresponding PICTURE clause must be numeric and c a n i n c l u d e e d i t i n g c h a r a c t e r s . I f a P I C T U R E clause is not specified, the default is PIC 9.
LOGICAL Option
A LOGICAL data item assumes only the values true or f a l s e . W h e n t h i s o p t i o n i s s e l e c t e d , Q u e r y U p d a t e d i s p l a y s t h e t r u e / f a l s e c o n d i t i o n r a t h e r t h a n t h e v a l u e o f t h e d e s c r i b e d d a t a . A c o r r e s p o n d i n g
PICTURE clause must be numeric.
COMPLEX Option
A COMPLEX data item is an ordered pair of signed or u n s i g n e d r e a l c o n s t a n t s ; t h e fi r s t r e p r e s e n t s t h e r e a l p a r t o f t h e c o m p l e x n u m b e r a n d t h e s e c o n d represents the imaginary part of the complex number.
A corresponding picture clause must be numeric and c a n i n c l u d e e d i t i n g c h a r a c t e r s . I f a P I C T U R E clause is not specified, the default is PIC 9.
