You can key the cuu of your choice in the first screen line just to the right of the constant
'CUU' or position the cursor anywhere on one of the list of available DASD's (shown as
cuu=volser in up to 7 columns beginning on screen line 3) and pressing enter. To refresh the
list of available DASD’s displayed to be based on a new poolname, enter the desired
poolname to the right of the constant ‘POOL’, clear any value found to the right of the
constant ‘CUU’, and press enter.
The VTOC Screen is displayed when the TVTO transaction-id and either a cuu or volser is
entered from a blank CICS screen or from a successful selection made from the HELP screen.
Screen line 1 includes the cuu, volser, and DASD model for the unit being displayed as well as
