<h1>General Features</h1>
<ul>
<li> Is a general compiler, apart from simulation, contains nothing specific
to the four instruction architecture.
<li> Four instruction architecture is defined in FIC_Base.inc .
<li> Allows an unlimited number of symbols that each hold a 64 bit signed integer.
<li> Allows an unlimited number of parameterised macros to be defined.
<li> Macro Defintions can can be nested.
<li> Macros and Symbols can be arrrayed/indexed.
<li> Case insensitive.
<li> N pass compiler (N defined in PASSES, current pass in PASS)
<li> Simulator has tested most features.
</ul>

<h1>Commands</h1>
<hr>
<font color=green><pre>
#define [MacroName] [ [ARG1] [,[ARG2]]... ]
{
[BLOCK]
}
</pre></font>
<blockquote>
Defines a parameterised macro. Arguments are literally included.<br><br>
EG If we have<br>
#define STW X { out ROM, INSTR_STW + (X); }<br>
Then<br>
STW PC;<br>
Expands to<br>
out ROM, INSTR_STW + (PC);<br><br>
argc always contains the number of arguments passed to the macro.
</blockquote>
<hr>
<font color=green><pre>
[MacroName] [ [ARG1] [, [ARG2] ]... ] ;
</pre></font>
<blockquote>
Expands Macro [MacroName] with given arguments.
</blockquote>
<hr>
<font color=green><pre>
#if ( [Condition] )
{
[Block]
}
</pre></font>
<blockquote>
Executes block once if condition evaluates to true (1)
</blockquote>
<hr>
<font color=green><pre>
while ( [Condition] )
{
[Block]
}
</pre></font>
<blockquote>
Executes block repeatedly while condition evaluates to true (1)
</blockquote>
<hr>
<font color=green><pre>
message [symbol] ;
</pre></font>
<blockquote>
Outputs value of symbol;
</blockquote>
<hr>
<font color=green><pre>
error [message]
</pre></font>

</blockquote>
<hr>
<font color=green><pre>
dump [StartExpression], [StopExpression];
</pre></font>
<blockquote>

from (start) to (stop - 1) inclusive.
</blockquote>
<hr>
<font color=green><pre>
out [symbol], [expression];
</pre></font>
<blockquote>
Places result of [expression] into memory map at [symbol],
then increments [symbol].
</blockquote>
<hr>
<font color=green><pre>
#include "[filename]"
</pre></font>
<blockquote>
Recursively includes [filename]
</blockquote>
<hr>
<font color=green><pre>
simulate;
</pre></font>
<blockquote>
Simulates four instruction machine.
</blockquote>
<hr>
<font color=green><pre>
stop;
</pre></font>
<blockquote>
Halts compilation.
</blockquote>
<hr>
<font color=green><pre>
[Symbol] = [Expression];
</pre></font>
<blockquote>
Evaluates [Expression], and assigns result to [symbol];
</blockquote>
<hr>
<h1>Expressions</h1>
The following C binary operators are supported:<br>
+ - * / % == != <> > < >= <= << >> & | ^ && ||<br>
<br>
The following C unary operators are supported:<br>
+ - !<br>
<br>
The following C values are supported for hex numbers,
decimal numbers and characters:<br>
0xDDDD DDDD 'C'<br>
<br>
Operator precedence is NOT supported so use brackets to resolve:<br>
((1 + (2 * 3)) == 6)<br>
but<br>
((1 + 2 * 3 ) == 9)<br>
<br>
Symbol arrays are supported:<br>
A[1 + 2] == A[3]<br>
<hr>
<h1>Comments</h1>
C++ and C comments are supported:<br>
//C++ comment<br>
/* C Comment */<br>
<hr>
<h1>FIC_BASE.INC</h1>
<ul>
<li> Declares word sizes and values for the four instructions.
<li> Declares macros for:
<ul>
<li> Primitive simple, instructions.
<li> Labels
<li> Variables
<li> Writable code necessary for indexed access to memory, namely
MEMCPY, MEMSET, PUSH, POP, CALL and RET.
<li> If constructs
<li> Loop constructs
<li> Function constructs
</ul>
<li> Partitions memory into Registers, RAM and ROM.
<li> Assumes MAIN function is defined by user code, and calls it.
<li> Implements a data stack (STACK_DATA) and program counter stack (STACK_PC).
these run into each other (STACK_DATA increases, STACK_PC decreases)
<li> If, Loop and Function constructs use frames to localise jumps.
<li> Jumps within functions are relative.
<li> Jumps in to and out of functions are absolute.
<li> Defines numbers -100 through +100 inside ROM
( NUM[-100] through NUM[+100] )
</ul>
<hr>
<H1>FIC_LIB.INC</H1>
Implements
<li> Unsigned multiply - UMULT.
<li> Unsigned divistion - UDIV.
<li> Unsigned decimal output - OUTPUT_DECIMAL, uses UMULT and UDIV.
