1712 The assembler was tested by assembling the entire instruction table, while
1713 at the same time testing labels and directives.
1714 The test file was assembled and then the binary and .dsm files were inspected
1715 manually by checking their size and content.
1716 None of this testing is automated and files are inspected by hand.
1717 The test files and results can be found in the Supporting Material.
