* $FG,2$lock{}$FG$ can be used to apply asm $FG,2$LOCK$FG$ prefixes to code for safe multicore read-modify-write accesses. The code bracked with have $FG,2$LOCK$FG$ asm prefix's applied to relevant insts within. It's a little shoddy. See $LK,"::/Demo/MultiCore/Lock.CPP"$.

* There is a function called $LK,"MSize",A="MN:MSize"$() which gives the size of an object alloced off the heap. For larger size allocations, the system rounds-up to a power of two, so $GREEN$MSize()$FG$ lets you know the real size and you can take full advantage of it.

* You CAN $LK,"Free",A="MN:Free"$() a $GREEN$NULL$FG$ ptr. Useful variants of $LK,"MAlloc",A="MN:MAlloc"$() can be found $LK,"Here",A="MN:CAlloc"$. Each task has a heap and you can $GREEN$MAlloc$FG$ and $GREEN$Free$FG$ off-of other task's heaps, or make an independent heap with $LK,"HeapCtrlInit",A="MN:HeapCtrlInit"$(). See $LK,"HeapLog",A="MN:HeapLog"$() for an example.

* The stk does not grow because virtual mem is not used. I recommend allocating large local vars from the heap. You can change $LK,"MEM_DFT_STK",A="MN:MEM_DFT_STK"$ and recompile $GREEN$Kernel$FG$ or request more when doing a $LK,"Spawn",A="MN:Spawn"$(). You can use $LK,"CallStkGrow",A="MN:CallStkGrow"$(), but it's odd. See $LK,"::/Demo/StkGrow.CPP"$.
