h6. [[OS_DynamicArea]] h6(. » Shrinkable Dynamic Areas h4. Notes Shrinkable areas are created using [[OS_DynamicArea 0]] with bit 9 of R4 set. They may be shrunk by the kernel when free memory is about to be exhausted. Shrinkable areas must have a handler routine. A new handler reason code is used for Shrinkable areas: [[Dynamic Area TestShrink|TestShrink]]. Shrinkable areas should be used sparingly due to the load on the kernel whenever free memory must be calculated (e.g. for every [[Wimp_SlotSize]] call). h4.
