Directories and Directory Access

DFM supports DDM directories and read-only directory access functions. You can read the directory entries themselves, and their associated DDM attributes, when you list these directories:

Selected lists of target data sets
PDSE directories and PDS directories

Note: For record files, the file size shows the number of records in the file. For stream files, the file size shows the number of bytes in the file. (If the file size is unknown to z/OS®, a size of 0 is shown.)

DFM does not support the MKDIR command for directories, nor does it support member names that do not comply with z/OS PDSE or PDS naming restrictions. For example, a client file named AFILE could be copied to an z/OS directory, but AFILE.TXT could not.

Renaming within an z/OS directory is possible, but the full z/OS path name must be given. For example, you could perform a RENAME with the following command:

 
   RENAME IBMUSER.PDSE(A) IBMUSER.PDSE(B)

However, the following RENAME would not work:

 
   CD IBMUSER.PDSE (or DFMDRIVE ASSIGN IBMUSER.PDSE)
   RENAME A B
