acl_register_host_request_func

	status.i4.v = acl_register_host_request_func(request_func.f.v)

	This routine registers a host request function for the Accelerator
	Command Language (ACL).  A host request function is the means for
	an ACL script (through the use of the "host_request" command) to
	pass a request to the program which executed the script.

	request_func	null terminated symbol name
			(called as follows:
			 status.i4.v = request_func(request_string.i1a.r))

	This function returns ACNET status values as follows:

	CLIB_OK			success
	CLIB_DUPREQ		a function has already been registered

	This function requires the following include files:

	acl_h, acnet_errors.h
