BCPL
(Basic CPL) A British systems language developed by Richards in 1969 and descended from ref="module.php?name=Lexikon&file=search&eid=1&query=CPL">CPL (Combined Programming Language). BCPL is low-level, typeless and block-structured, and provides only one-dimensional ref="module.php?name=Lexikon&file=search&eid=1&query=arrays">arrays. Case is not significant, but conventionally reserved words begin with a capital. Flow control constructs include: 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. It has 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 ref="module.php?name=Lexikon&file=search&eid=1&query=call-by-value">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. The first BCPL ref="module.php?name=Lexikon&file=search&eid=1&query=compiler">compiler was written in ref="module.php?name=Lexikon&file=search&eid=1&query=AED">AED.
