  JCL  /J-C-L/  n.  1.  IBM's  supremely  {rude}  Job  Control  Language. 
  JCL  is  the  script  language  used  to  control  the  execution  of  programs  in 
  IBM's  batch  systems.  JCL  has  a  very  {fascist}  syntax,  and  some  versions 
  will  for  example,  {barf}  if  two  spaces  appear  where  it  expects  one 
  Most  programmers  confronted  with  JCL  simply  copy  a  working  file  (or  card 
  deck),  changing  the  file  names  Someone  who  actually  understands  and 
  generates  unique  JCL  is  regarded  with  the  mixed  respect  one  gives  to 
  someone  who  memorizes  the  phone  book.  It  is  reported  that  hackers  at 
  IBM  itself  sometimes  sing  "Who's  the  breeder  of  the  crud  that  mangles  you 
  and  me?  I-B-M,  J-C-L,  M-o-u-s-e"  to  the  tune  of  the  "Mickey  Mouse  Club" 
  theme  to  express  their  opinion  of  the  beast.  2.  A  comparative  for  any 
  very  {rude}  software  that  a  hacker  is  expected  to  use  "That's  as  bad  as 
  JCL."  As  with  {COBOL},  JCL  is  often  used  as  an  archetype  of  ugliness  even 
  by  those  who  haven't  experienced  it  See  also  {IBM},  {fear  and  loathing}. 
  A  (poorly  documented,  naturally)  shell  simulating  JCL  syntax  is 
  available  at  the  Retrocomputing  Museum  `'.
