Summary

Privileges
System manager
Function
Displays DSNAME, VOLSER, DSORG, RECFM, BLKSIZE, LRECL UNITS (space), PRIMARY (space) for each DDNAME selected.

Syntax

DISPLAY DSNAMES [pattern] or

D DSN [pattern]

Where

pattern is a simple pattern that limits the number of DDNAMES displayed. A simple pattern is a character string with no wildcard or special characters. Any DDNAME whose first characters match the pattern is displayed.

Usage notes

  • DISPLAY DSNAMES is available as of version 8.0 of Model 204.
  • DISPLAY DSNAMES is not supported under VSE or CMS.
  • Space information is displayed only for Model 204 files and only those that are open. The space value displayed is for the entire Model 204 file only. If the file is a multi-dataset file, each dataset is listed but not the space allocated to each dataset - only the space allocated to the entire Model 204 file across all datasets. If the Model 204 file is a single dataset file, then the space listed will be the space allocated to that single dataset but will appear only on the line that represents the entire Model 204 file.
