  PL/I
       
          Programming Language One.
       
          An attempt to combine the best features of {Fortran}, {COBOL}
          and {ALGOL 60}.  Developed by George Radin of {IBM} in 1964.
          Originally named NPL and Fortran VI.  The result is large but
          elegant.  PL/I was one of the first languages to have a formal
          {semantic} definition, using the {Vienna Definition Language}.
          {EPL}, a dialect of PL/I, was used to write almost all of the
          {Multics} {operating system}.  PL/I is still widely used
          internally at {IBM}.  The PL/I standard is ANS X3.53-1976.
       
          PL/I has no {reserved word}s.  Types are fixed, float,
          complex, character strings with maximum length, bit strings,
          and label variables.  {Array}s have lower bounds and may be
          dynamic.  It also has summation, multi-level structures,
          {structure assignment}, untyped pointers, {side effect}s and
          {aliasing}.  {Control flow} constructs include goto; do-end
          groups; do-to-by-while-end loops; external procedures;
          internal nested procedures and blocks; {generic procedure}s
          and {exception handling}.  Procedures may be declared
          {recursive}.  Many implementations support {concurrency}
          ('call task' and 'wait(event)' are equivalent to {fork}/join)
          and compile-time statements.
       
          {LPI} is a PL/I {interpreter}.
