16C. stack organisation
-----------------------
To store all local and global variables, the run-time system of an
executable generated by Amiga E allocates a chunk of memory,
from which it takes some fixed part to store all global variables.
The rest will be dynamically used as functions get called.
as a function is called in E, space on the stack is reserved
to store all local data, which is released upon exit of the function.
That is why having large arrays of local data can be dangerous when
used recursively: all data of previous calls to the same function
still resides on the stack and eats up large parts of the free stack
space. However, if PROCs are called in a linear fashion, there's
no way the stack will overflow.
Example:

global data:		10k (arrays etc.)
local data PROC #1:	 1k
local data PROC #1:	 3k

the runtime system always reserves an extra 10k over this for normal
recursion (for example with small local-arrays) and additional buffers/
system spaces, thus will allocate a total of 24k stack space
