- The Teletype Model 33 lacked curly braces and other characters due to ASCII 1963 limitations, influencing early UNIX and C development.
- Early C relied on terminals like the Teletype Model 37 that supported braces; UNIX V4 added kernel translation for Model 33 using backslash escapes.
- C evolved from B and BCPL, which used alternative syntax like $(\) for blocks before adopting braces, with lasting impacts on naming conventions.
