The existing methods (the IGZTUNE macro and the SPOUT and WSCLEAR runtime options) for space management and tuning are not available under Language Environment. Language Environment services now control space management and tuning using the RPTOPTS, RPTSTG, STORAGE, ANYHEAP, BELOWHEAP, HEAP, LIBSTACK, and STACK runtime options.
With VS COBOL II, storage tuning is done at the process level; under Language Environment storage, tuning is done on an enclave basis. For details of space management and tuning with Language Environment, see the Language Environment Programming Guide.
