  Ada  n.  A  {{Pascal}}-descended  language  that  was  at  one  time 
  made  mandatory  for  Department  of  Defense  software  projects  by  the 
  Pentagon.  Hackers  are  nearly  unanimous  in  observing  that  technically, 
  it  is  precisely  what  one  might  expect  given  that  kind  of  endorsement  by 
  fiat;  designed  by  committee,  crockish  difficult  to  use  and  overall 
  a  disastrous,  multi-billion-dollar  boondoggle  (one  common  description 
  wss  "The  PL/I  of  the  1980s").  Hackers  find  Ada's  exception-handling 
  and  inter-process  communication  features  particularly  hilarious. 
  Ada  Lovelace  (the  daughter  of  Lord  Byron  who  became  the  world's  first 
  programmer  while  cooperating  with  Charles  Babbage  on  the  design  of  his 
  mechanical  computing  engines  in  the  mid-1800s)  would  almost  certainly 
  blanch  at  the  use  to  which  her  name  has  latterly  been  put  the  kindest 
  thing  that  has  been  said  about  it  is  that  there  is  probably  a  good  small 
  language  screaming  to  get  out  from  inside  its  vast,  {elephantine}  bulk. 
 
 
 
  From  The  Free  On-line  Dictionary  of  Computing  (13  Mar  01)  [foldoc]: 
 
  Ada 
 
    (After  {Ada  Lovelace})  A  {Pascal}-descended 
  language,  designed  by  Jean  Ichbiah's  team  at  {CII  Honeywell} 
  in  1979,  made  mandatory  for  Department  of  Defense  software 
  projects  by  the  Pentagon.  The  original  language  was 
  standardised  as  "Ada  83",  the  latest  is  "{Ada  95}". 
 
  Ada  is  a  large  complex,  {block-structured}  language  aimed 
  primarily  at  {embedded}  applications.  It  has  facilities  for 
  {real-time}  response,  {concurrency},  hardware  access  and 
  reliable  run-time  error  handling.  In  support  of  large-scale 
  {software  engineering},  it  emphasises  {strong  typing},  {data 
  abstraction}  and  {encapsulation}.  The  type  system  uses  {name 
  equivalence}  and  includes  both  {subtype}s  and  {derived  type}s. 
  Both  fixed  and  {floating-point}  numerical  types  are  supported. 
 
  {Control  flow}  is  fully  bracketed:  if-then-elsif-end  if 
  case-is-when-end  case,  loop-exit-end  loop,  goto.  Subprogram 
  parameters  are  in  out  or  inout.  Variables  imported  from 
  other  packages  may  be  hidden  or  directly  visible.  Operators 
  may  be  {overloaded}  and  so  may  {enumeration}  literals.  There 
  are  user-defined  {exception}s  and  {exception  handler}s. 
 
  An  Ada  program  consists  of  a  set  of  packages  encapsulating 
  data  objects  and  their  related  operations.  A  package  has  a 
  separately  compilable  body  and  interface.  Ada  permits 
  {generic  package}s  and  subroutines,  possibly  parametrised 
 
  Ada  support  {single  inheritance},  using  "tagged  types"  which 
  are  types  that  can  be  extended  via  {inheritance}. 
 
  Ada  programming  places  a  heavy  emphasis  on  {multitasking}. 
  Tasks  are  synchronised  by  the  {rendezvous},  in  which  a  task 
  waits  for  one  of  its  subroutines  to  be  executed  by  another. 
  The  conditional  entry  makes  it  possible  for  a  task  to  test 
  whether  an  entry  is  ready.  The  selective  wait  waits  for 
  either  of  two  entries  or  waits  for  a  limited  time. 
 
  Ada  is  often  criticised,  especially  for  its  size  and 
  complexity,  and  this  is  attributed  to  its  having  been  designed 
  by  committee.  In  fact  both  Ada  83  and  Ada  95  were  designed 
  by  small  design  teams  to  be  internally  consistent  and  tightly 
  integrated.  By  contrast,  two  possible  competitors,  {Fortran 
  90}  and  {C++}  have  both  become  products  designed  by  large  and 
  disparate  volunteer  committees.
