Operand descriptions

The operands described in this section can be specified in any order.

FROM(indd)

See the discussion of this operand on the DISPLAY statement in DISPLAY operator.

ON(p,m,f)

Specifies the position, length, and format of a numeric or character field to be used with this operation.

p specifies the first byte of the field relative to the beginning of the input record. p is 1 for the first data byte of a fixed-length record and 5 for the first data byte of a variable-length record as illustrated in the following (RRRR represents the 4-byte record descriptor word):

    Fixed-length record    |    Variable-length record
    | D | A | T | A | ...  |    | R | R | R | R | D | A | T | A | ...
 p=   1   2   3   4        | p=   1   2   3   4   5   6   7   8

m specifies the length of the field in bytes. A field must not extend beyond position 32752 or beyond the end of a record. The maximum length for a field depends on its format.

f specifies the format of the field as shown in the following table:

Field formats of the ICETOOL UNIQUE operator Format Code	Length	Description
BI	1 to 256 bytes	Unsigned binary
FI	1 to 256 bytes	Signed fixed-point
PD	1 to 32 bytes	Signed packed decimal
ZD	1 to 32 bytes	Signed zoned decimal
CH	1 to 4000 bytes	Character
CSF or FS	1 to 32 bytes	Signed numeric with optional leading floating sign
UFF	1 to 44 bytes	Unsigned free form numeric
SFF	1 to 44 bytes	Signed free form numeric
Note: See Data format descriptions for detailed format descriptions.

For a ZD or PD format field:

F, E, C, A, 8, 6, 4, 2, and 0 are treated as equivalent positive signs. Thus the zoned decimal values F2F3C1, F2F3F1, and 020301 are counted as only one unique value.
D, B, 9, 7, 5, 3, and 1 are treated as equivalent negative signs. Thus the zoned decimal values F2F3B0, F2F3D0, and 020310 are counted as only one unique value.
Digits are not checked for validity.

ON(VLEN)

See the discussion of this operand on the DISPLAY statement in DISPLAY operator.

VSAMTYPE(x)

See the discussion of this operand on the COPY statement in COPY operator.

UZERO

See the discussion of this operand on the OCCUR statement on OCCUR operator.
