Do you have a product in mind that is being barred by lack of this support? I'd like to hear more about your business case.

However, the communcation channel between the wrorker and the RSK master, IUCV, is a source of some problems. Would it be possible to replace the IUCV worker LD with one based on APPC? Our reasons for asking for this are the following: 1) APPC is supported across a multitude of IBM platform, while IUCV commincation is supported only on VM. APPC would allow RSK-controlled worker machines to execute on, say, OS/2 workstations. 2) APPC would allow worker machines to reside on other, separate VM systems, from the RSK master. IUCV also allows for comminication betwwen separate VM images, but requires extra software like PVM to do the actual communication function. This adds an extra layer of cost and complexity to such applications. 3) VM already provides a well documented and tested CSL library for coding APPC aware applications. There is no such library for IUCV, forcing each user to either develop their own CSL for IUCV or code the worker application in Assembler, using native IUCV macros. 4) While there are many valid reasons for requiring that RSK servers be coded in assembler (for performance and other reasons), RSK worker machines can be coded in whatever language best meets the requrements the worker machine is to address. Using a standard, well-defined and tested, communications method like APPC (in the form of it's standard CSL), would make this task much easier for vendors and end users alike, imho.
