FIELDS Instruction

A SORT or MERGE instruction must be followed by a FIELDS instruction which specifies the fields on which the input file is to be sorted or merged.

A fields instruction takes the following form:


where the parameters are:

Parameter Description
start The starting position of the field in the record, counting in bytes from 1
length The length of the field (bytes)
type The type of data in the field. See the section Field Types .
order The ordering of output, which can be either of: A - ascending D - descending

You can specify up to 100 fields by repeating the parameter set (start, length, type and order). Use commas to separate the parameters and the parameter sets.
