This variable is used when you are writing a Common Gateway Interface (CGI) program in COBOL. It allows you to suppress the output of the HTML header.
Set CGI_AUTO_HEADER to 0 (off, false, no) if you want to suppress the output of the HTML header. This can be useful when you want to execute a CGI program and include its output into an existing flow of HTML text. For example, with server-side includes, or SSI, you can instruct the Web server to execute a subprogram in the manner of CGI and then incorporate its output right into the HTML document before sending it to the requesting client. The default value is 1 (on, true, yes).
