What does Db2 precompiler do?

The Db2 precompiler scans a program and copies all of the SQL statements and host variable information into a DBRM (database request module). The precompiler also returns source code that has been modified so that the SQL statements do not cause errors when you compile the program.

What is the use of commit statement in Cobol Db2 program?
