Maybe POGO handles such issues. 4KByte and more requires some call >checkstack for paging reasons. Do you mean 4 KB per routine, or total stack space? What will that checkstack function do? Why is it needed? I don't know these levels of detail in the implementations/hardware. I had the feeling, that the paging is done automatically behinds the scenes (say when the stack pointer crosses a 4 KB boundary, the paging mechanism of the OS will be called). Probably this is all too naive. Cheers, Dieter
