The copy books are expanded only in the compilation phase
of the application execution. But we would need the details
from DCLGEN in the pre-compilation phase, wherein the DB2
statements in the COBOL application is separated and put in
a DBRM. The equivalent COBOL ‘CALL’ statements are replaced
for the DB2 statements in the COBOL code. Then the
compilation of the COBOL and binding of the DBRM is done,
before being linked and executed.
Hence the INCLUDE statement is used instead of COPY
statement, an adaptation for the pre-compilation stage. The
same reason applies to the usage of INCLUDE in case of
SQLCA inclusion.
