set maxcc and set lastcc work directly in the jcl without forward slashes

In a COBOL progam you can set the RETURN-CODE system variable which will populate that value in the LASTCC and MAXCC variables in the JCL. You can check LASTCC (the return code of the last step) or MAXCC (the highest return code for all steps) implicitly by coding the COND= statement on the...

Here's a link which may be helpful and a snippet from the page. http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/igy3lr00/6.2.26?ACTION=MATCHES&REQUEST=open&TYPE=FUZZY&SHELF=&DT=20011206182158&searchTopic=TOPIC&searchText=TEXT&searchIndex=INDEX&rank=RANK&ScrollTOP=FIRSTHIT#FIRSTHIT...

As a caveat, careful your subscript doesn't ever extend beyond the last element or you'll start referencing procedure division code, with extremely unpredictable results.

I think interactive debugger requires sp compiled by not linked source residing locally on a workstation in order to see activated dubug pull-downs. That is, the debugger actually requires addressibility to C code on the local workstation. (When sp's are compiled, a C deck is created.) After...

This is a bind parameter ISOLATION. Most common is CS (Cursor Stability.)

In an OS/390 platform, you can use DDF (Distributed Data Facility.) This is an OS/390 address space. This requires binding remote packages locally in the BIND PLAN PKLIST parm by specifying the remote node, collection name, package name or wildcard. You CONNECT in you application code to the...

Using z/OS DB2 V6., I need to determine if a stored procedure is stopped or started by running DML. I can't locate a status-type column in SYSROUTINES. Where is DB2 getting this information when a DSN -DISPLAY PROCEDURE command is issued? Thanks.

Is it always a good idea to index foreign keys or should this be done only when parent rows are deleted? That is, do indexes on foreign keys improve Select, Insert, or Update performance. I've heard 'do it always' and 'only when parent rows often deleted'. If a general rule is to use indexable...

Use the IBM-supplied sample program DSNTIAUL to create load cards. This is an unload program. Although there will not be any data, the program will still create the load cards. If there isn't a one-to-one correspondence between VSAM files and tables (and there shouldn't be if the model is...

Depends if the 2nd file is appended to the first or acutally 'merged'. The queston doesn't state what the index key is. Perhaps it's customer number not date. So, the merged file woudl have cust 1, date1, date2....cust2, date1, date2. What we do know is that both files contain May data. Are...

Rather than writing a program, why not use a product like SYNCSORT to do the merge? Also, if you have Easytrieve Plus, he'll do about the same thing and will give you a report if you want it. I'm not sure what either of these products will do with an ISAM file. You may have to repro them down...

In a nutshell, though I'm sure someone will have a more scientific definition, JCL(Job Controll Language) executes a progam (compiled and linked machine code) within a load library, providing a number of resources to that program: File names (data files, work files), input parameters, and other...

I've tried different combinations without success. Placing cursor on the page I want to being paging on, hitting next page one time, coninuous the next; then inserting page numbers with continue from next section selected or not selected. I'll still get page numbering starting at the first page...
