Data Memory Allocation

Find Here after the memory allocation for every USAGE clause

"Format Native" means that the data may be stored in either little or big-endian representation, depending on the platform on which the program is running.

BINARY / COMPUTATIONAL

Attribute	Description
Size	Depends on number of “9”s in `PICTURE` and the ”binary- size” setting of the configuration file used to compile the program. See binary-size description. The default value of `bin-opt:[yes/no]`is `bin-opt:no` When set to yes: Enables binary operation optimization. The `–bin-opt` optimizations are enabled by use of the `–O` compiler flag.
Format	`bin-opt-strict:[yes/no]` When set to yes: Causes `-fbin-opt` binary operation optimization to be strictly respected. The `binary-byteorder` setting of the configuration file is used to compile the program.
Negative value allowed	If PICTURE contains “S”
PICTURE allowed	Yes

BINARY-CHAR / BINARY-CHAR SIGNED

Attribute	Description
Size	1 byte
Format	Native
Negative value allowed	Yes
PICTURE allowed	No

BINARY-CHAR UNSIGNED

Attribute	Description
Size	1 Byte
Format	Native
Negative value allowed	No
`PICTURE` allowed	No

BINARY-C-LONG / BINARY-C-LONG SIGNED

Attribute	Description
Size	Allocates the same amount of storage as does the C language “long” data type on that computer; typically this is 32 bits, however it can be 64 bits.
Format	Native
Negative value allowed	Yes
`PICTURE` allowed	No

BINARY-C-LONG UNSIGNED

Attribute	Description
Size	Allocates the same amount of storage as does the C language “long” data type on that computer; typically this is 32 bits, however it can be 64 bits.
Format	Native
Negative value allowed	No
`PICTURE` allowed	No

BINARY-DOUBLE / BINARY-DOUBLE SIGNED

Attribute	Description
Size	Allocates a traditional double-word of storage (64 bits)
Format	Native
Negative value allowed	Yes
`PICTURE` allowed	No

BINARY-DOUBLE UNSIGNED

Attribute	Description
Size	Allocates a traditional double-word of storage (64 bits)
Format	Native
Negative value allowed	No
`PICTURE` allowed	No

BINARY-LONG / BINARY-LONG SIGNED / SIGNED-LONG / SIGNED-INT

Attribute	Description
Size	32 Bits
Format	Native
Negative value allowed	Yes
`PICTURE` allowed	No

BINARY-SHORT / BINARY-SHORT SIGNED / SIGNED-SHORT

Attribute	Description
Size	16 Bits
Format	Native
Negative value allowed	Yes
`PICTURE` allowed	No

BINARY-SHORT UNSIGNED / UNSIGNED-SHORT

Attribute	Description
Size	16 Bits
Format	Native
Negative value allowed	No
`PICTURE` allowed	No

COMPUTATIONAL-1

Attribute	Description
Size	Allocates a word of storage (32 bits)
Format	Single-precision floating-point
Negative value allowed	Yes
`PICTURE` allowed	No

COMPUTATIONAL-2

Attribute	Description
Size	Allocates a double-word of storage (64 bits)
Format	Double-precision floating-point
Negative value allowed	Yes
`PICTURE` allowed	No

COMPUTATIONAL-3 / PACKED-DECIMAL

Attribute	Description
Size	Allocates 4 bits per “9” in the `PICTURE` plus a (trailing) 4-bits field for the sign, rounded up to the nearest byte.
Format	Packed decimal
Negative value allowed	If `PICTURE` contains “S”
`PICTURE` allowed	Yes

COMPUTATIONAL-4

Attribute	Description
Size	If the `pack-comp-4` setting of the configuration is set to yes, the size is computed like a `COMPUTATIONAL` as if the binary-size setting of the configuration is set to “1— 8”. If the `pack-comp-4` setting of the configuration is set to No, the size is identical to `COMPUTATIONAL`. See binary-size description. Depends on setting of `bin-opt:[yes/no]` Default is: `bin-opt:no` When set to yes: Enables binary operation optimization. The `–bin-opt` optimizations are enabled by use of the `–O` compiler flag.
Format	`bin-opt-strict:[yes/no]` When set to yes: Causes `-fbin-opt` binary operation optimization to be strictly respected. The`binary-byteorder` setting of the configuration file is used to compile the program.
Negative value allowed	If `PICTURE` contains “S”
`PICTURE` allowed	Yes

COMPUTATIONAL-5

Attribute	Description
Size	Depends on number of “9”s in `PICTURE` and the ”binary-size” setting of the configuration file is used to compile the program. See binary-size description.
Format	Native
Negative value allowed	If `PICTURE` contains “S”
`PICTURE` allowed	Yes

COMPUTATIONAL-6

Attribute	Description
Size	Allocates 4 bits per “9” in the `PICTURE`, as is done with `COMPUTATIONAL-3` data items. However, the data may not be `SIGN`'ed, so there is no trailing 4-bit field for the sign. When the number of digits is odd, the high-order 4-bits contains a 0. To calculate the size of a `comp-6` data item, divide the `PICTURE` size by 2 and round up.
Format	Packed Decimal
Negative value allowed	No
`PICTURE` allowed	Yes

COMPUTATIONAL-X

Attribute	Description
Size	The size is computed like Signed `COMPUTATIONAL` as if the ”binary-size” setting of the configuration is set to “1— 8” and `SIGN`'ed rules are used event if the Picture does not include “S”. Value of `bin-opt:[yes/no]` - default is No. `bin-opt:no` When set to yes: Enables binary operation optimization. The `–bin-opt` optimizations are enabled by use of the `–O` compiler flag.
Format	`bin-opt-strict:[yes/no]` When set to yes: Causes `-fbin-opt` binary operation optimization to be strictly respected. The `binary-byteorder` setting of the configuration file is used to compile the program.
Negative value allowed	If `PICTURE` contains “S”
`PICTURE` allowed	Yes

DISPLAY

Attribute	Description
Size	Depends on `PICTURE` One character per X, A, 9, period, $, Z, 0, *, S (if `SEPARATE CHARACTER` specified), +, - or B symbol in `PICTURE`; Add 2 more bytes if DB or CR symbol used.
Format	Byte
Negative value allowed	If `PICTURE` contains “S”
`PICTURE` allowed	Yes

POINTER / PROGRAM-POINTER

Attribute	Description
Size	32 Bits or 64 Bits depending memory model used
Format	Native
Negative value allowed	No
`PICTURE` allowed	No
