Path names in the QDLS file system

Each component of the path name can consist of just a name.

For example:
```
     /QDLS/FLR1/DOC1
```
or a name plus an extension (similar to a DOS file extension), such as:
```
     /QDLS/FLR1/DOC1.TXT
```
The name in each component can be up to 8 characters long, and the extension (if any) can be up to 3 characters long. The maximum length of the path name is 82 characters, assuming an absolute path name that begins with /QDLS.
The directory hierarchy within QDLS can be 32 levels deep. If / and QDLS are included as the first two levels, the directory hierarchy can be 34 levels deep.
The characters in names are converted to the code page of the job when the names are stored unless data area Q0DEC500 has been created in the QUSRSYS library. If this data area exists, then the characters in names are converted to code page 500 when the names are stored. This function provides compatibility with the behavior of the QDLS file system in previous releases. A name may be rejected if it cannot be converted to the appropriate code page.
