Existing TCAM applications that use the OS/VS COBOL SEND and RECEIVE statements run under Language Environment with one exception: the QUEUE runtime option of OS/VS COBOL is not supported. (The QUEUE runtime option is used only in an OS/VS COBOL program with a RECEIVE statement in a CD . . . FOR INITIAL INPUT.)
For more information, see IBM VS COBOL for OS/VS, and IBM OS/VS COBOL Compiler and Library Programmer's Guide.
