ALIST TSO Command

ALIST is a TSO command that provides a better display of the same information that the IBM supplied LISTALC command shows, which is all datasets allocated to the current TSO User session.  Where LISTALC only shows the dataset name, ALIST includes the DD Name, dataset organization (DSORG), allocation type, volume serial number, and dataset name.

ALIST is a product of Lionel Dyck at Rockwell International in Seal Beach, CA.  This version is from the older CBT tape, version #249.

Installation

In order to assemble ALIST, you need some specialized macros, also provided by Lionel, but in a separate file on the CBT249 image.  It also requires the IHAQDB macro, which is available in the MVS 3.8j source material (library SYM1-1).  I have gathered all the required macros and the source, and placed them in a single jobstream, along with a simple help text.  The jobstream - alist.jcl - is contained in the archive alist.tgz [MD5: 8D79382E9BAC6A53A0A3D609342D0E0F].  Download the archive and extract the jobstream (WinZip on Windows/?? or tar on Linux).  Submit the jobstream to assemble and link the single load module for ALIST into SYS2.CMDLIB and copy the help text into SYS2.HELP.  If you don't have SYS2.CMDLIB defined, you will need to modify the jobstream to specify a different target load library.  Also if you do not have SYS2.HELP defined, you may modify the jobstream to place the help information into SYS1.HELP.

Utilizing ALIST

ALIST is simple to use.  It has no operands.  When issued it will display all datasets currently allocation to your TSO User session.
