+# Broadcom TSS WHOHVOL REXX Script
+WHOHVOL REXX can interactively identify, using a single command, who has access to all owned VOLUME resources within TSS. This REXX is an example of the “art of the possible” in using REXX with TSS. 
+
+The challenge:  Provide a simpler method for reviewing who has VOLUME resource access based on all volume resources owned.
+
+Background:  Previously, to review all Volume access, the mainframe cybersecurity professional needed to manually perform the following steps: (1) List all volume ownership - TSS WHOOWNS VOL(*), (2) Manually build all of the TSS WHOHAS VOLUME(xxxxxx) commands, and (3) Submit as a batch job and review the output.  TSO WHOHVOL performs those steps interactively and provides the resulting report into a temporary dataset, placing the professional into edit mode and allowing for them to copy/paste/create or process as desired.    
+
+# Using
+Sample scripts for each product are located in the directory that shares its name. If you cannot find a particular use case, [please open an issue](https://github.com/BroadcomMFD/broadcom-product-scripts/issues/new).
+
+What to do:   
+1.	Upload the WHOHVOL.rexx.txt as WHOHVOL into your CLIST/REXX library.
+2.	Execute:  TSO WHOHVOL          
+3.	WHOHVOL only takes a few seconds to complete and produce the report for your review.
