21 Handles first pass of assembly
22
23 First pass involves the following:
24
25 1. read all lines from the main source file, following all "include"
26 directives as appropriate
27 2. parse each line into a symbol, operation code, and operand as appropriate
28 3. each operand is evaluated for syntax and futher for value if there are
29 multiple addressing sizes available; any undefined or not fully resolved
30 value will default to the largest addressing size available (16 bit)
31 4. addresses are assigned to every symbol defined in the assembly
32 5. macros are defined and expanded at this pass
