When you create drill-down graphs, keep these points for specific operating environments in mind:

All Operating Environments

• You can specify the URL= suboption with PATH=, BODY=, or both. Used with PATH=, the URL= value can be a URL or the keyword NONE, which specifies that no information from the PATH= option appear in the links or references.
  
  
• If you transfer your files to a different operating environment, you also need to consider case in links in your HTML files. For example, if you create GIF files on a host where file names are uppercase and then FTP the files, the file names may be lowercase on the target platform. In this case, you must rename the GIF files so that they match the SRC= values in the HTML files.
  

OS/390 Operating Environment

• You must specify PATH=, GPATH=, or both.
  
  
• If you store your HTML or GIF files as members in a partitioned data set, the PATH= value must be a PDSE, not a PDS. You can allocate a PDSE within SAS as shown in this example:

       filename pdsehtml '.example.htm'
                dsntype=library dsorg=po
                disp=(new, catlg, delete);
  

  Also, you should specify valid member names for the HTML files (without extensions).
  
  

• If you store your GIF files in a PDSE, you can submit the following OPTIONS statement to prevent error messages about file extensions for graph member names:

          options fileext=ignore;
 

CMS Operating Environment

• You must specify PATH=, GPATH=, or both.
  
  
• You must use URL= in the PATH= option because CMS file names do not form valid URLs.
