If you use a TSO command, CLIST, or REXX exec, ISPF puts the variables
described in
Table 1 in the shared pool
for the TSO command, CLIST, or REXX exec to use.
Table 1. TSO command/CLIST/REXX exec variables
(output)| Variable Name |
Description |
Length in Characters |
|---|
| ZDLBLKSZ |
Data set block size |
5 |
| ZDLCAT |
Cataloged status; one of these:
- 0
- Data set is cataloged on volume ZDLVOL.
- 2
- Data set is cataloged on a volume other than ZDLVOL and is either:
- on volume ZDLCAT but uncataloged
- on volume ZDLCAT and defined in a user catalog that is connected
to the master catalog, but not in the normal catalog search path
The name of the user catalog is in
ZDLCATNM.
- 4
- Data set is uncataloged on volume ZDLVOL.
- 6
- Data set is not cataloged on any volume and is uncataloged on
volume ZDLVOL.
- 8
- Data set is not available on volume ZDLVOL. This status is returned
for data sets that have been either migrated or deleted.

When you select the Display Total Tracks option, and the data set
list is displayed either in SPACE view or in TOTAL view, ISPF also
puts the variables described in
Table 2 in
the shared pool for the TSO command, CLIST, or REXX exec to use.
Table 2. TSO command/CLIST/REXX
exec additional variables (output)| Variable Name |
Description |
Length in Characters |
|---|
| ZDLSIZET |
Total tracks of all data sets in the list |
19 |
| ZDLSIZTX |
Total tracks of all data sets in the list, not
including the tracks of excluded data sets |
19 |
| ZDLDST |
Total number of data sets in the list (available
for all display views) |
6 |
| ZDLDSX |
Total number of data sets in the list, not including
the excluded data sets |
6 |
Note: ISPF cannot calculate reliable space utilization values for
VSAM or BDAM data sets. Therefore, question marks (?) are returned
in variables that report space utilization for these data sets.
A TSO command, CLIST, or REXX exec can set these variables and
place them in the shared pool to communicate with the Data Set List
utility (option 3.4).
