In CICS/VSAM every file that is accessed should be defined in FCT. we have CICS READ, WRITE, BROWSE commands for VSAM files. How does it work with DB2 tables. It know it has to do with the plan. Please expain with examples.
1 4615i know the stpes 2 create an executable CICS/DB2 cobol code. 1. DB2 Precompiler converts the SQL Statements into COBOL API statements and creates another member with Acess plans. CodeA results in CodeB (code with API calls) & CodeC ( Access Plans ) 2.Code B is compiled/linked 2 create an exceutable.(codeE) 3.Now CodeC is binded to the database on which CodeE will be run. Can somebody provide me the sample JCLs for precompile/compile/link/bind.

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.
