INTEGRATING APPLICATIONS
Avoiding Conflicting Box Names
• The SCREEN COBOL requester program sends a message to the
General Server that tells it to open a file. The requester
program does not use the file name, but uses the box name
instead.
• The General Server accepts the message from the requester
program and looks at the assign specification to determine
which physical file is assigned to a specific box name.
• The General Server then opens the assigned physical files,
using the access mode indicated in the assign specification.
Figure 11-3 illustrates this process.
