Simple questionnaire using CGI subroutines
This example is a program that exchanges information between a WWW Server and a WWW Browser by using CGI subroutines.
Outline
The Entry Field, Check Box, and Radio Button values are received from the WWW browser, a Web page for processing result output is created on the WWW server according to the received information, and the created Web page is displayed on the WWW browser.
Supplied programs
CGIBASIC.COB (COBOL source program)
SAMPLE01.HTM (Web page for invoking application)
SAMPLE01_1.HTM (Web page for processing result output)
COBOL85.CBR (initial file for execution)
CGI subroutines used
COBW3_INIT, COBW3_GET_VALUE, COBW3_SET_CNV, COBW3_PUT_HTML, COBW3_PUT_TEXT, and COBW3_FREE
Program compilation
Compile the program by using the COBOL32 command in which the -M option and -I option (for specifying the folder for storing the CGI subroutine library) are specified.
The -I option need not be specified if the CGI subroutine library file (COBW3.cbl) was already copied from the COBOL-installed folder to the current folder.
COBOL32 -M -I"C:\Program Files\Fujitsu NetCOBOL for Windows\COBOL" CGIBASIC.COB
Program linkage
Import libraries F3BICWSR.LIB, F3BICIMP.LIB, and MSVCRT.LIB are added.
LINK /OUT:CGISMP01.EXE CGIBASIC.OBJ F3BICWSR.LIB F3BICIMP.LIB MSVCRT.LIB
Conditions for program execution
The path to the Web application for which the FORM tag ACTION attribute is specified in the Web page for invoking the application (CGISMP01.HTM) must be changed to a virtual path on the WWW Server to be actually used.
Program execution
Copy the CGISMP01.EXE, SAMPLE01.HTM, SAMPLE01_1.HTM, and COBOL85.CBR files to the specified folder on the WWW Server.
From the WWW browser, enter the URL of the WWW Server and specify SAMPLE01.HTM. A simple questionnaire screen is displayed.
Enter or select necessary data, and click the [Invoke CGI Program] button. The entered data is sent to the WWW Server, and the processing result is displayed on the WWW Browser.
To cancel the entered data before the data is sent to the WWW server, click the [Reset Values] button.
The processing result HTML Web page should be displayed noting which data you entered and which check box and radio button you selected.
