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 .
