Replacing partially present fields

When replacing partially present fields be aware of the following points.

The following figure is an example of a partially present field on a REPL call based on the DBD and PSB in Retrieving missing fields.

Figure 1. Example of a partially present field on a REPL call
Physical segment before update has fields LL, EMPNO, EMPNAME, BIRTHD, and ADDRESS (bytes 43 to 50). After the update, the ADDRESS field goes from bytes 43 to 52.

The 'LL' field is changed from 50 to 52 by DL/I to accommodate the change in the field length of ADDRESS.
