Whilst “B” only had the “word” as a type it did have, at last in the version I used, on the Honeywell L66/GCOS machines, a set of functions to manipulate character strings.

Correct... The first versions anyway before B/NB/C I do not think that is 100% correct. B and early UNIX sort of come about at the same time. B (and its pseudo model - BCPL) has only one data type (a word) and that works because UNIX was originally implemented on a word addressed machine. NB/C comes out when the Ken starts moving to the 11 which was byte addressed, as opposed to word addresses of it's predecessors.
