In nested programs, specifies the program-id at which to start generating DB2 interface code. Any nested program encountered
before the program-id is ignored and no DB2 interface code is generated. You must specify a program-id in the COBOL source
code; otherwise, a compile error results. If you specify IGNORE-NESTED without a parameter, the program-id defaults to the
program name with the filename extension replaced by .CBL.
Syntax:
IGNORE-NESTED=program-id
IGNORE-NESTED
NOIGNORE-NESTED
