ISPF Allocation Functions should allow more xBYTE sizes

I have an open RFE to get additional size specifications in JCL and IDCAMS. This is to have ISPF Panels to provide the same size entries

Currently panels like 3.2 DataSet Utility allow for Bytes, KiloBytes and MegaBytes

I would like to see the addition for the following sizes
G or GB for Gigabyte
T or TB for Terabyte
P or PB for Petabyte
E for EB or EX or Exabyte
Z or ZB for Zettabye
Y or YB for Yottabyte

I would also like to see an enhancement to the ISPF HELP Panel on this information. As well as an additional Help Panel on how to determine how much storage is needed for a file. Most shops are using 3390 architecture. So it should be based on that.

In Option 3.4 I would like to see on the dataset list an '*' asterisk next to dataset not allocated in TRKS/CYL. When you use PF11 on the panel to view the summary data, when you get to the last one, you only see TRKS allocated. An '*' would give the user a chance to see that maybe the file was not allocated in TRKs/CYLs and to use I for more information.

The last part for ISPF 3.4 would be to allow the selection of seeing the file allocations in the dataset list in TRKs/CYLs/xB (MB, GB, TB, etc.)

Data set list options
Initial View
1 1. Volume
2. Space
3. Attrib
4. Total

Add a 5th option - Show Allocation In _B Where the user could enter
K M G T P E Y Z
If this option selected and nothing entered in the _B field, default should be Bytes

That way a manual calculation to cyls, or MB, GB, etc. could be avoided

    What is the largest possible Z/OS dataset allocation at the moment? That's not easily answered. But assuming and Extended Format dataset with VOL=(,,,59) and 1TB empty volumes it's a Z/OS hard limit of ~59TB for a dataset. That is a long way from from a PB through to YB! Good to future proof though if feasible.
    It would be useful for ISPF 3.4 to show an option KB, MB, GB etc value as opposed to just Total TRKS though.

    Creating a new RFE based on Community RFE #93348 in product z/OS.
