/*
|
|
*
|
|
* TestCGI.PRG
|
|
* Harbour Test of a CGI/HTML-Generator class.
|
|
*
|
|
* 1999/05/30 First implementation.
|
|
*
|
|
* Tips: - Use ShowResults to make dynamic html (to test dynamic
|
|
* results, put the exe file on CGI-BIN dir or equivalent);
|
|
* - Use SaveToFile to make static html page
|
|
*
|
|
* 1999/05/31 Initial CGI functionality.
|
|
* 1999/06/01 Translated %nn to correct chars.
|
|
* 1999/06/02 Dynamic TAG matching routines (inspired on Delphi).
|
|
* First attempt to convert Delphi's ISAPI dll of WebSites'
|
|
* Function List
|
|
* (See http://www.flexsys-ci.com/harbour-project/functions.htm)
|
|
* 1999/06/11 List can be viewed online at
|
|
* http://www.flexsys-ci.com/cgi-bin/testcgi.exe
|
|
* 1999/07/29 Changed qOut() calls to OutStd() calls.
