Interfacing Realia+VACOBOL modules

[cobp]

Is it possible to invoke a Realia COBOL module(dll) from a VA COBOL program.

We had an application developed on VACOBOL and it allows users to write their own custom modules and can combine with our application. One of our customer had a Realia COBOL compiler and he wants to generate a dll file using Realia compiler and want to invoke it from the Visual age COBOL module.

Hi,

CA-REALIA can work with an C- or Pascal- interface. It is created by using a C_ or P_ prefix in the name I think...

or when Realia takes control:

[DATA]
143700* TRANSFER CONTROL TO PASCAL OF C
143800*
143900*
144000 CALL 'MLI_XCTL_C_PROCEDURE-NAME' USING PARAMETERS
144100 CALL 'MLI_XCTL_P_PROCEDURE-NAME' USING PARAMETERS
144101 CALL 'MLI_XCTL_C' USING POINTER REST-OF-PARAMETERS
144102 CALL 'MLI_XCTL_P' USING POINTER REST-OF-PARAMETERS
[/DATA]

I guess you can find some examples on the following FTP site:

ftp://ftp.cai.com/pub/realia/Samples/

I hope this helps you.

Hi Crox,

Thanks for the information.
I need to invoke a CA Realia COBOL from a VA COBOL program. Using C interface, I could invoke a C program from the VA COBOL and which inturn could invoke the CA Realia COBOL program.
Do you know the calling convention for invoking the CA REALIA COBOL program from a C program. The C compiler used is MS-DEV VISUAL C++.

Hi,

In the ca-examples in the link there is a c-to-cobol example. It is not much to download even all of them. The file ctocobol.zip is probably what you are looking for in the real4 examples.
