* File printterm.c. This file contains routines for printing out lambda *
* terms. It is assumed that these routines will be needed in two *
* situations: printing out answers to queries and displaying terms as *
* needed by invocation of builtin goals. *
* The difference between these two situations is in the display of *
* free term variables. Only when displaying answers is an attempt made to *
* present these using sensible names: in this case, either the name in the *
* query is used or a concise name is cooked up. In the other situation, *
* the address of the variable cell is used as the name. *
* *
* Certain assumptions are relevant to avoiding name clashes. For local *
* constants, the assumption is that no constant names in user *
* programs begin with <lc- and end with >. The use of this idea is *
* buried inside the routine PRINT_writeHCName. *
* Violation of this condition is *not* checked. For term variables, the *
* assumption is that bound variables do not begin with _. *

* File printterm.h{c}. This file contains routines for printing out lambda *
* terms. It is assumed that these routines will be needed in two *
* situations: printing out answers to queries and displaying terms as *
* needed by invocation of builtin goals. *
* The difference between these two situations is in the display of *
* free term variables. Only when displaying answers is an attempt made to *
* present these using sensible names: in this case, either the name in the *
* query is used or a concise name is cooked up. In the other situation, *
* the address of the variable cell is used as the name. *
* *
* Certain assumptions are relevant to avoiding name clashes. For local *
* constants, the assumption is that no constant names in user *
* programs begin with <lc- and end with >. The use of this idea is *
* buried inside the routine PRINT_writeHCName. *
* Violation of this condition is *not* checked. For term variables, the *
* assumption is that bound variables do not begin with _. *

TABLES
======
The files in source/tables define the pervasive tables and instruction
format tables.
pervasives:
pervasives.h{c}
===============
Defines the pervasive tables for pervasive kinds, type skeletons
and constants. Note these files are automatically generated.
pervinit.h{c}
=============
Defines the initialization functions for pervasive tables: such functions
are necessary because the pervasive names in the system run-time have
special encoding in the simulator (source/simulator/mcstring.h{c}) for
garbage collection as opposed to simply C strings. These names have to
be laid out on the system memory upon system initialization.
instructions.h{c}
=================
Defines instruction formats and instruction opcodes.
Note these files are automatically generated.
