[TUHS] Re: Does anybody know the etymology of the term "word" as in collection of bits?

Bit-addressing is very helpful for manipulating characters in a word-organized memory. The central idea of my ancient (patented!) string macros that underlay SNOBOL was that it's more efficient to refer to 6-bit characters as living at bits 0,6,12,... of a 36-bit word than as being characters 0,1,2,... of the word. I've heard that this convention was supported in hardware on the PDP-10. In the IBM 7020 floats and ints were word-addressed. But those addresses could be extended past the "decimal point" to refer to bits. Bits were important. The computer was designed in parallel with the Harvest streaming "attachment" for NSA. Harvest was basically intended to gather statistics useful in code-breaking, such as frequency counts and autocorrelations, for data typically encoded in packed 5- to 8-bit characters. It was controlled by a 20-word "setup" that specified operations on rectangular and triangular indexing patterns in multidimensional arrays. Going beyond statistics, one of the operations was SQML (sequential multiple lookup) where each character was looked up in a table that specified a replacement and a next table--a spec for an arbitrary Turing machine that moved its tape at byte-streaming speed!
