You could put spaces in the middle of identifiers, keywords, and numbers, and the compiler ignored them. The language did not require spaces as separators anywhere. Spaces were only significant in Hollerith constants (what we'd call string literals today) and in columns 1-6. Columns 1-6 were reserved for line numbers, comment signifiers, and continuation marks.

was interpreted as assignment

   DOI = 1.1

Though contrary to urban legend it did not result in the loss of any rockets.
