Stanford Extended ASCII (SEASCII) is a derivation of the 7-bit ASCII character set developed at the Stanford Artificial Intelligence Laboratory (SAIL/SU-AI) in the early 1970s. [1] Not all symbols match ASCII.
Carnegie Mellon University, the Massachusetts Institute of Technology, and the University of Southern California also had their own modified versions of ASCII. [1]
Each character is given with a potential Unicode equivalent.

The underscore operator in SAIL source-code assignments printed as a left arrow in the Stanford variant of ASCII, but PDP-10 sites elsewhere just saw it as a plain underscore. However, its use as the assignment operator meant that it could not be used as an extended letter to make compound names more readable, as is now common in many other programming languages. The left arrow in the Stanford variant of ASCII was not the only unusual character.(NB. Shows a table of Stanford extended ASCII following that described in RFC 698.)
