As ever, you use this free program at your own risk.

Feel free to use the free software on this site but please honor the copyright.

This code is used, via a LOAD statement, by many Abbydale Systems Programs to define 31-bit DCBS that are used by the programs.

The code is not executable but rather just a collection of the more common DCBS used by our programs.

These include:

  • SYSIN - Standard SYSIN DD card used by most of our programs.
  • SYSPRINT - Standard SYSPRINT DD card used by most of our programs.
  • INPUT - Standard SYSIN dataset used by most of our programs.
  • DIRIN - Used for reading a PDS directory by our programs.
  • SNAP - SNAP dump DCB used by our programs.
  • MQLOG - Used by our programs for writing a log for MQ programs.
  • CORRELID - Used by our programs to pass a CORRELID to MQ programs.
  • LONGMSG - Used by our programs to load a long message to a queue.
  • INTRDR - Standard internal reader DCB.

Obviously if your site needs to add or change any oft used DD names then care must be taken to ensure the dependant code is changed if any offsets are changed.

We recommend never changing the order of the SYSIN or SYSPRINT DCBS as these are very commonly used by our programs.

It should be noted that not all of the DCBs are used by all of our programs, however, the program documentation will indicate which ones, if any, are used by that particular program.
Link Description
 
This link will take you to the source code for ASLDCBS

The code itself is not executable




  This link will take you to a XMIT file that contains the z/OS libraries containing the ASLDCBS program and help files in IBM TSO TRANSMIT format. This file should be transferred to the z/OS system using a file transfer program. The file must be transferred as a BINARY file. It should be transferred as a fixed blocked, 80 byte file.

Once the file is on z/OS it will have to bereceived. To do this you use the TSO RECEIVE command. Please refer to the IBM RECEIVE command for details on the use of this TSO command.

Once this dataset has been RECEIVEd you will need to execute the UNPACK member. This will unpack all the TRANSMITTED datasets.

You do this by entering the following command on a TSO command line:

TSO EXEC 'install.ASLDCBS.PDS(UNPACK)'


Reply to the prompts and when the exec is complete read the $$INSTAL member to finish installing the facility.



  This link will display program assembly and link information for ASLDCBS.
