As shown in Figure 3-1 "Record Input and Output",
record input and output are processed after SORT-MERGE/XL is intialized and
before SORT-MERGE/XL is ended.
Figure 3-1 Record Input and Output
You can use record input or record output when you wish to alter the records.
Choose the input by record option when you want to sort a
set of input that is available to you one record at a time. This
happens when the records you want to sort are created within the
sorting program or when records are intended to be received interactively
(for example, if your program accepts input from a terminal). Record
input is only available for SORT/XL.
Choose the output by record option when you want to sort or
merge information during a program's execution without directly
storing the information. For example, use it if you want to display
a sorted list to a user's terminal, or if you want a chance to modify
the output before storing in a file.
