BLISS is a typeless word-oriented language like BCPL, so I am surprised to see it in this list. Also I am amused to hear VAX/VMS described as a mainframe operating system.
The string handling functions in chapter 20 require the programmer to pass around separate pointer and length arguments, which is not what I would call proper strings.
Also Pascal and BASIC compilers with several extensions, e.g. VMS Pascal and VMS BASIC.
