When using the data structure pointer even for small programs the memory is filled up quickly if no precautions were made. However, especially the possibility of dynamic variables is a fundamental feature of PASCAL, so that in the authors opinion it is of great importance to manage the further use of not-more-needed memory. In the present paper first methods are described how this can be done by the programmer. However, for a modern programming language it is a tall order to leave this important task to the user and, moreover, this has to be done for every program and subprogram separately. Therefore, in a second chapter methods will be described, how the compiler can manage the dynamic memory recovery in PASCAL. In contrast to known methods here it has been looked for a compromise between optimal recovery and time efficiency. The author hopes, that the fundamental necessity of recovering memory not longer needed will be recognized and entered in the report and, that more compilers with this ability will come into the market.
