Hi Adrian,
I found some old files that can be used to demonstrate one way to use VMCF.? These were actually used in production back in the day.? A virtual machine server (VMSINK) would host CMS files used by various applications that were invoked by users running CMS.? Using VMCF, the application programs could request that the server open a file, read or write record(s), and close the file, among other functions.? In this way, multiple userids could access the same file, and with proper coding in the application program even support multiple users writing to the same file.? VMSINK served to serialize the file i/o.? These programs would probably work in VM/370 Sixpack with no changes except that possibly the FORM=E specification should be removed from the FSCB macros.? But the point isn't so much to try to run them as to use them as a guide to setting up VMCF as a sender and a receiver.
I uploaded the programs to the files area, called 'vmsink.zip'.? It contains the server which sets up VMCF, and the requestor which uses VMCF to request services from the server.?? The programs are not large and perhaps they can help you see how to use VMCF, as one example.? There is a README file within to guide you through the components and a bit more detail.
Regards,
Bob
