Answer Posted / tej
Precompilation separates the SQL statements and non-SQL
statements of an application program.
From the precompilation step onwards the original source
code will be contained in two separate physical components.
The non-sql part of the program will have all the
sql-statements commented out by the precompiler and and
replaced with cobol call statements.
The colection of SQL that was extracted will be placed in a
DBRM(Database Request Module).Precompiler also places a
consitency token in both of its outputs.
