Before a Web application using an ISAPI subroutine can be executed, the following run-time environment must be set in an environment variable or in a run-time initialization file (COBOL85.CBR).
To use a different run-time initialization file depending on the business, place each business application in a different folder and assign a different virtual directory to each business using IIS to configure it as a separated process. Additionally, link F3BICBDM.obj into each application so that the run-time initialization file of a folder storing the application can be referenced.
