you can use sequential files, but they have to be ESDS.

2. EQivalent XCTL,LINK in cobol
there is nothing equivalent to XCTL in cobol
Link is equivalent to CALL

I agree with first 2 answers of above post. The 3 rd answer is....

The Relation ship between CICS and DB2 depends on implementation. Generally CICS initiates the process and DB2 serves so that we can say CICS master and DB2 slave. But it purely depends on implementation method.

Bye,
Reddy.

Hi,
Please correct me if wrong. icon_wink.gif
What I think is all the CICS commands in the CICS-COBOL program are converted in to equivalent COBOL Calls by the CICS TRansalator.
Is this right?
and yes, we can not use flat files in CICS. We can use any type of SAM files, DB2 and ADABAS.

Cheers

hi,

The equivalent statement for xctl in cobol is CHAIN. But it is only in cobol 74 only.

hi,
Cics supports only with VSAM datasets. if you wants to work with seq. file, you should use Entry Sequenced DataSet(ESDS).

You CAN use SAM files in CICS but it's not recommended. The vehicle for this is the extra-partition TDQ. Many yrs ago these Qs were used to write transaction logs to tape because disk space was VERY expensive.

The problem with its use is that the entire CICS region that issued the I/O goes into a wait state when the system waits for the I/O to complete. Not a good way to win friends and influence people, especially ops people.
