Incase of KSDS, file will have '.CL' as the last qualifier
of the Dataset. This helps to identify, whether the File is
Flat file or VSAM. However, the VSAM Files can be created
without this Qualifier or with Flat file naming Convention.
For ex: WIP161.DDIO.XPD -- DDIO FILE for Xpeditor. This
file can be either VSAM or Flat File. In such cases, it's
difficult to distinguish.
Since most of the VSAM Files are created with '.cl' as the
last qualifier, files can be identified quickly inthe JCL
with this qualifier.
