Re: Logical File with Field being substringed as a Key

[mcdonald_sb@xxxxxxxxxx]

This is an Example of a Logical being built over a Flat File.
File, Record Format and Field are all the same in the Flat File.

SubString can only be defined as input only but you can update the
Main field with the subst funtions.

In this example Keys are used in key list but updates are made to
Field ERRTRX

Hope this Helps

      A          R ERRTRX                    PFILE(ERRTRX)

      A            RECERR         2   I      SST(ERRTRX 11 2)
      A            CLMERR        20   I      SST(ERRTRX 15 20)
