16F. compiler buffer organisation and allocation
When you get the error 'workspace full' (very unlikely), or want
to know what really happens when your program is compiled, it's useful
to know how EC organizes its buffers.

A compiler, and in this case EC needs buffers to keep track of all sorts
of things, like identifiers etc., and it needs a buffer to keep the
generated code in. EC doesn't know how big these buffers need to be.
for most buffers, like the one for various strcutures, this is no
problem: if the buffer is full while compiling, EC just allocates a
new piece of memory and continues. Other buffers, like the one for
the generated code, need to be a continuous block of memory that doesn't
move while compiling: EC needs to make a pretty good estimate of
this buffersize to be able to compile small and large sources alike.
To do this, EC computes the needed memory relative to the size of
your source code, and adds a nice amount to it. This way, in 99% of the
cases, EC will have allocated enough memory to compile just about any
source, in other cases, you'll get the error and have to specify more
memory with the '-m' (ADDBUF) option.

Experiment with different types and sizes of example-sources in combination
with the '-b' (SHOWBUF) option (see  0D ) to see how this works in practice.
