Q7.
Why does the WWW browser display the “Content-type” declaration?
A7.
If the COBW3-DMODE-DBG is specified in COBW3_INIT, the “Content-type” and
other header information is displayed by the WWW browser as debug information.
It is not displayed if COBW3-DMODE is not specified.
Q8.
Why does the message of the file download appear when I execute the Web
application?
A8.
This type of message may be output if the “Content-type” declaration is incorrect in
the Web application. Check the “Content-type” declaration for an error.
Q9.
Do you have any caution when writing a COBOL program during creation of Web
application?
A9.
You can use almost all COBOL functions directly in a Web application. However, you
cannot use the following screen operation functions.
•
•
•
Presentation file module (screen handling module)
Screen handling module.
ACCEPT/DISPLAY function (However, you can use the environment variables and
date and time control functions.)
For details of Web parameter reception, reference, and process result output, see
Chapter 3 “How To Use SAF Subroutines.”
Q10.
How can I set up environment variables required for WWW server startup?
A10.
Add the required environment variables to the environment setup file, and specify
the environment setup file name in the “env” parameter of the line where
“COBOL_Init” is set in the “obj.conf” file. Then, restart the NES.
Otherwise, store the initialization file for execution (COBOL85.CBR) which defines the
required environment information in the same folder as the Web application (.dll).
