Memory allocation of non-dialog work process in UNIX and Windows

Memory allocation of non-dialog work process in UNIX

In UNIX, if Roll memory gets full Heap memory is occupied and if heap memory gets full extended memory is used.

But
in windows it is different, after roll memory (ztta/roll_first) is
filled the work process uses Extended memory, after extended memory is
fill then remainder of roll memory ( ztta/roll_area - ztta/roll_first)
is used soon..

Unix or Unix like systems	Windows
Roll Memory up to  ztta/roll_area	Roll Memory up to ztta/roll_first
| | \|/	| | \|/
Heap Memory  up to abap/heap_area_nondia or HM Exhaust	Extended Memory up to ztta/roll_extension or EM Exhaust
| | \|/	| | \|/
Extended Memory up to ztta/roll_extension or EM Exhaust	Roll Memory Remainder of ztta/roll_area
	| | \|/
	Heap Memory up to abap/heap_area_dia or HM Exhaust
