The following table from the sample configuration file lists some standard CGI environment variables. However, you can pass any variables that your Web server supports. (For more information about environment variables, see the CGI area
at the World Wide Web Consortium Web site.)
Note: These SAS macro variable names are suggestions only; you do not need to use these exact names.
| Environment variables |
SAS macro variable |
Description |

transmitting the client request. |
| SERVER_PORT |

Extra path information after the script passed to a
CGI program. |
| PATH_TRANSLATED |
_PATHTRN |
Local filename of PATH_INFO. |

case, a duplicate of _URL, another macro variable passed
to the Dispatcher program. |
| DOCUMENT_ROOT |
_DOCROOT |
Directory from which Web documents are served. This
variable is unreliable. |
| QUERY_STRING |
_QRYSTR |
