All:
I am not trying to pour cold water on any ideas or dis-credit anyone, that's not me . I have a weird kinda legacy issue I am trying to solve. Basically, COBOL STC calling Assembler subroutines. The STC(s), are single threaded or single TCB and the real issue is we need them to run multi-threaded (in C terminology ) or multi-tasking . The both use Sockets ..So I was exploring , trying to figure out what the easiest and most supportable way to do this. There is only me doing this …and money is short…same ole same old story. This is why I asked the question. Regards, Scott From: John Gilmore Sent: Thursday, May 8, 2014 11:59 AM To: IBM Mainframe Discussion List The distinction between COBOL's distinction of WORKING-STORAGE and LOCAL-STORAGE is essentially the same as the PL/I and then C distinction of static and automatic storage. As far as I can judge from earlier posts in this thread the shared facility is not a dynamic shared control block; it is a read-only table; and the serialization of accesses to such a table is required only if it is replaced from time to time DURING the execution of the multithreaded application. Serialization is possible from, although not within, COBOL. One writes a pair of simple COBOL-callable assembly-language to do it; and it is also possible and useful to write such a pair of subroutines to LOAD and DELETE [load module or program object] tables. In general, then, Mr. Perryman and I disagree, as we often have. His generic strictures, which would interdict all mixed-language applications, are simplistic.
