Answer / deepak gairola
DCLGEN(Declaration Genrator) is used to generate DB2
equivalent Cobol Datatypes. We can write a cobol Db2
program without using it but we will have to declare cobol
variables in our Program and for sure it need to be DB2
Equivalent... but it is preffered to use DCLgen as it gives
you the accurate... equivalent... of db2 datatype...and it
enhances the performance no doubt...
For Sql Datatype is Name Varchar(20).
so cobol equivalent is
01 Name.
49 Name-len PIC s9(04) comp.
49 Name-text pic x(2).

DCLGEN is used to create the cobol copy book. But it is not
mandatory to use DCLGEN for that. We can hardcode that
cobol variables. For the purpose of reduce the manual
errors we use DCLGEN to create those copy books.

DELGEN is a declaration generator to generate the DB2
equivilant COBOL variables . It will improve the
performance of the program. Here only we can give the
NULLIND as 'YES' the automatically when ever null values
are specified in DB2 then it will move SPACES or ZEROS to
the COBOL variables
