If we keep the DCLGEN structure for a table in a copybook
and include it in the COBOL program using the COPY
statement, will there be any impact during compilation or
at any stage of program execution?

DCLGENs need to be processed by the precompiler. The
precompiler will comment out the SQL and insert the
appropriate COBOL definitions.
If the COPY directive is used, the COBOL compiler will flag
the SQL with syntax errors.

What do you mean by between and in? Is between inclusive of specified range values?
SET is the ANSI standard for variable assignment, SELECT is not. SET can only assign one variable at a time, SELECT can make multiple assignments at once. If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one) When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value) As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.
