Once the parsing takes place, the output can be placed in any one of many formats. One
format the output data can be placed in is in the form of selected records. The parsing
takes place. If the selection criteria are met, the data—record at a time—are gathered.

A variation of the record selection process occurs when only the context is selected, not
the entire record.

Yet, another variation occurs when the record—once selected—is merged on output with
another record.

There are undoubtedly many other variations other than the ones that are suggested here.

Fig. 4.5.1 shows the possibilities that have been discussed.

Recasting the Output Data

Once the parse and selection process has been completed, the next step is to physically
recast the data. There are many factors that determine how the output data are to be
physically recast. One of the factors is how much output data are there. Another factor is
what the data will be used for. And there are undoubtedly many other factors as well.
