Making single variables a record and then passing that single record ( not
by value , but by reference )  may reduce stack requirement .


New stack size ( 20 * 1024 * 1024 ) may not be effective . There is a
necessity to check that the new definition is accepted .

There may be a large recursive call number to exhaust the stack . If there
is such a recursive call , elimination of this recursive call may reduce
the required stack size .

If local data size is large , moving them into a record , and allocating
that record in heap may reduce stack requirement .


Thank you very much .
