01-MAY-93   MJWR  Generate version specific to MSDOS & Windows
16-Sep-93   MJWR  Add DELETE and DELETEA macros for deleting
                  storage allocated with 'new'.  These macros
                  also set the pointer to NULL when done.
                  DELETEA is used for deleting ARRAYS of storage.
                  DELETE is used for all others.  For example:

                  int *oneInt = new int;
                  int *intAry = new int[20];
                  ...
                  DELETE(oneInt); // == delete oneInt; oneInt = NULL;
                  DELETEA(intAry);// == delete [] intAry; intAry = NULL;
06-Jun-94    MJWR DELETE and DELETEA macros conflict with Microsoft Foundation
                  Classes.  Consider these obsolete and use LIMDEL and LIMDELA
                  respectively.
