 What? No description of the translation? Just curious as to what one should
 expect from such translation, as it proceeds from a totally block-structured
 (but not necessarily separate-compilable) language to a non-block-structured
 (but independently-compilable) language. My guess is that in going from P to
 C, internal routines must get their environment preserved  -- presumably --
 by "struct's", which carry externally-known identifiers inward; otherwise, I
 suspect much indirection on the part of globally-declared pointers playing
 the role of a 'display'. The only alternative would be much resort to para-
 meter passing, which overhead I suspect this translator seeks to avoid.
