Basic CPL. Richards 1967. British systems language, a descendant of CPL and the inspiration for B and C. BCPL is low-level, typeless and block-structured, and provides only one-dimensional arrays. Case is not significant, but conventionally reserved words begin with a capital. Flow control: If-Then, Test-Then-Else, Unless-Do, While-Do, Until-Do, Repeat, Repeatwhile, Repeatuntil, For-to-By-Do, Loop, Break and Switchon-Into-Case-Default-Endcase.
BCPL has conditional expressions, pointers, and manifest constants.
BCPL had both procedures: 'Let foo(bar) Be command' and functions: 'Let foo(bar) = expression'. 'Valof $(..Resultis..$)' causes a compound command to produce a value. Parameters are call-by-value. Program segments communicate via the global vector where system and user variables are stored in fixed numerical locations in a single array.
BCPL was used to implement the TRIPOS OS, which was subsequently reincarnated as AmigaDOS.
Oxford BCPL differed slightly: Test-Ifso-Ifnot, and section brackets in place of $( $).
