    Hello, is there a possibility to use Vs Code /Cobol with DB2? Do you have any example?

    Which COBOL is this? I came back to the language and I can´t believe that most programming is still done employing the old fixed-format source code, and archaic editors. Useful additions related to screen usage, by the way. Thank you for sharing.

    I have not yet register to have access to zOS mainframe. Just syntax checking right now my COBOL/CICS programs. May I ask if there is expiration to mainframe access? Can I try Stored Procedures, Channel and Containers instead of COMMAREA. ALso, finding a nice debugger. Separating presentation logic, business logic, and data access programs to try web services using JSON files.

    You say COBOL have no idea about DB2, but DB2 knows COBOL because Stored Procedures can be written in COBOL. I'm right? Thank you!

    I was a system programmer back in the 70s. I remember updating the CICS tables for new programs, terminals & databases. You had to shit down CICS and re load it to bring in the new tables. CICS 1.3 under DOS/VSE. The first 4 characters of the 3270 stream were blanked out so an application could plug in the 4 character program name of the next program to run when any PFAID key or ENTER key was pressed.

    Your reference to the SQLDA reminds me of the following, which may be useful to you. I worked from 1981 with SQL/DS, supporting customers in the DOS/VSE and VM/CMS implementations. When DB2 came along, I used the same approach there, and it worked well. The original SQL/DS manuals stated explicitly that dynamic SQL could only be exploited in Assembler and PL/I. However, the constructs for PREPARE and the rest were there in COBOL. I tried it out, and this it what the books should have said. “You can build dynamic SQL, but the target COBOL variables referenced in the SELECT list must match the data coming in as the results of the FETCH”. In other words, it reflected the fact that COBOL couldn’t allocate storage dynamically in response to the values in an SQLDA. An early customer in. CICS/DOS/VS wanted to display a screen with many fields that the user could use in various combinations to narrow down their search, but the result list was always the same. So the SQL statement was built up in sections, starting with “SELECT NAME, RANK, NUMBER” After that, each field input from the screen was tested, and if it was not blank, the appropriate additional WHERE clause was added. No attempt was made to allow for AND/OR sophistication. Once the statement was complete, it was PREPped and run. This was used by number of other customers, and when DB2 came along it worked in exactly the same way. I don’t know if the DB2 books made the same restrictive statement, but it was directed at the limitations of COBOL, not of the data base or the SQL interface.

    Nice to see enterprise COBOL can be learned by those interested to learn mainframe. I used to teach COBOL using PC version separate from the JCL because my students then are not allowed to have access to the terminals connected to mainframe.

    I worked on a CICS system (utility customer service) back in the 70s and 80s, when most of the transactions were written in Assembler; the majority of which were limited to 12K bytes. The mainframe probably had 8MB of storage - and was supporting up to 2000 terminal operators - with under half second response.. Migrating to Cobol and Command Level was quite a revolution.

    I 'retired from CICS' 16 years ago after working with it for 26 years. Fascinating to see the zOS elements which were barely beginning to appear when I signed off! One minor observation: the start rather implies that CICS is for the finance industry only. Its true power is its flexibility across all business areas (manufacturing, commerce, government), and across a huge variety of enterprises from tiny (CICS on a 370/125 with 128K) to enormous.
