-X index-def [ ,index-def ...]

index-def

This specifies the main key first, and then the sub-key.

• Format of index-def

  pos.len typ opt

pos

This specifies the position of the index field in a byte position.

len

This specifies the length of the index field in byte.

typ

This specifies the data format of the index field.
The data formats and the lengths of the index field are shown as follows.

Type	Data format		typ	Length (byte)	Meaning
Character	ASCII code		asc	1-254	CHARTYPE of NetCOBOL
	Unicode UCS-2 form (Note 1)		uc2	2-254 (Multiples of 2)	CHARTYPE of NetCOBOL
		Big endian	u2b	2-254 (Multiples of 2)	CHARTYPE of NetCOBOL
		Little endian	u2l	2-254 (Multiples of 2)	CHARTYPE of NetCOBOL
	Unicode UTF-32 form (Note 2)		u32	4-252 (Multiples of 4)	CHARTYPE of NetCOBOL
		Big endian	u3b	4-252 (Multiples of 4)	CHARTYPE of NetCOBOL
		Little endian	u3l	4-252 (Multiples of 4)	CHARTYPE of NetCOBOL
	Unicode UTF-8 form		ut8	1-254	CHARTYPE of NetCOBOL

NOTES

1. Byte order follows the specification of the environment variable BSORT_UCS2TYPE.

2. Byte order follows the specification of the environment variable BSORT_UTF32TYPE.

opt

This specifies the operation of the index field.
The operations that can be specified are shown below. Always specify "e" for the final segment.

opt	Meaning
a	It sorts data in ascending order.
d	It shows duplicate key specification in the index.
