• (I) an immediate operand, which is unchanged;
• (A) an absolute address, which is unchanged;
• (R) a relative address, which is relocated;
• (E) an external address, which is resolved
  • look at the last 3 digits of the number that follows E and it will tell you where else it is used.
  • follow until you hit 777

All absolute addresses need to be put into the memory map & are not mutable

companies will be created a community will be created with pizza and trophies we will be a gatekeeper

1. Go through first lines of modules (every 3 lines) and create symbol table
2. Create the memory map

error's I'm not handling

• (√) If a symbol is multiply defined, print an error message and use the value given in the first definition.
• (√) If a symbol is used but not defined, print an error message and use the value zero.
• (√) If a symbol is defined but not used, print a warning message and continue.
• (√) If an address appearing in a definition exceeds the size of the module, print an error message and treat the address given as 0 (relative).
• (√) If an address appearing in a use list exceeds the size of the module, print an error message and treat the address as the sentinel ending the list.
• (√) If an address on a use list is not type E, print an error message and treat the address as type E.
• If a type E address is not on a use list, print an error message and treat the address as type I.

count which module you're in

count which of the 3 parts of a module you're in

count how long that part is

TODO

• Fix issue's with line 69 in linker.js
• Add support for last error type
• Add to npm
• Translate to Python
