Figure 9-2 Transferring Files With InterAxcess Several Levels Deep

Record and Field Selection

Record selection and field selection are features that allow you to

transfer only the records and fields you specify. This feature is part of

the PWRFROM3XB command. Record selection and field selection are not

mutually exclusive functions of ETU, although it's not necessary to use

them together.

NOTE: Record and field selection can be used only with externally-defined
host physical files.

About Creating Auxiliary Storage Pools

The Record and Field Selection feature within the PWRFROM3XB command will

not work properly if you define one or more additional Auxiliary Storage

Pools on the AS/400. This is because ETU creates temporary work files in

the library QTEMP, which is always located in Auxiliary Storage Pool #1

(which comes with OS/400). If you create an additional Auxiliary Storage

Pool, ETU cannot create the work files associated with the data file that

is stored in any newly created Auxiliary Storage Pools.

If you do create a new Auxiliary Storage Pool, you can simulate record

and field selection in a file transfer operation by creating a logical

file or and open query file and transferring those files.

Transferring Selected Fields

When you transfer a physical file from the host to a micro with the

PWRFROM3XB command, you have the choice of transferring all the fields in

the file, or, using field selection, transferring only the fields you

select. You can also specify the order in which the data will reside in

the micro file.

For each field you select to transfer, supply information to the

following parameters, found under the heading FLDSEL (field selection) on

the PWRFROM3XB prompt screen. The parameters are:
