Also, the 1700 linking and program loading were done at the same time,
the linker had to traverse threaded references and perform relocation
on those that needed it.  I created  a portable implementation of the
linker some time ago (the assembler is on hold until my retirement).

Although in a virtual-memory environment no relocation is needed at
program load time.
