Difference in behavior for dynamically called RENT programs

VS COBOL II programs use a different copy of WORKING-STORAGE for each call under the VS COBOL II run time, however, under Language Environment the same copy of WORKING-STORAGE is used for each call. These different situations occur when the following conditions are true: In addition, the programs enter their initial state when run under the VS COBOL II runtime library. However, when running under Language Environment the programs are entered in their last-used state, unless there is an intervening CANCEL.
