<p>The SetEnv directive allows you to set an environment variable that is
passed on to CGI scripts. See <a href="rzaieenvvar.htm">Environment variables on HTTP Server</a> for
more information.</p>

<dd><ul><li>The <em>variable</em> parameter is any valid EBCDIC characters except the
equal sign (=), the null-terminator (X'00') and blank (X'40'). The name must

The case is preserved when lowercase characters are specified. Valid values
include all EBCDIC characters. The value must be enclosed in quotation marks
if it contains any non-alphanumeric character or blanks. Lowercase characters
for the library names will not work if this directive is used to change the
library list. When changing the library list values, the libraries need to
be separated by a semicolon. </li>
