    writer: &mut W,

Write the user’s program as a tape image file.

Errors

• A tape block is longer than will fit into an 18-bit offset value
• The program is larger than the TX-2’s physical memory
• A block’s origin and length mean that it would extend past the end of ther TX-2’s physical memory.
• Failure to write the output file.
