2 Creating Core Routines That Sort and
Merge
This chapter describes two sets of operations: a basic sort and a basic merge. The
procedure development is described step by step. The complete examples are at the end of
the chapter. These core routines use a minimum set of operations to do a simple sort and
merge.
These examples take input from two files and return output to one file. They use the
standard ASCII collating sequence. Other options are discussed in other chapters.
