	You're expecting an AST in a compiler from the 50s?

	That might have involved having to punch an output deck of cards for
each compile, only to then feed that deck back into the reader for the next
phase of compilation.

	But kept things to one statement at a time, with the output being the
machine code for the processor -- possibly being punched to cards so it
could be loaded later.
