OMF-86 Symbol Tree. The OMF-86 symbol tree as built by SRU would appear
as follows (this is not a complete symbol tree):
SRU does not build tree nodes for variables that are dynamically allocated on the
stack at run-time, such as i and j within the delay() procedure. SRU has no way of
knowing where these variables will be at run time and therefore cannot build a
corresponding symbol tree entry with run-time addresses.
