  From  Jargon  File  (4.2.3,  23  NOV  2000)  [jargon]: 
 
  chain  1.  vi  [orig.  from  BASIC's  `CHAIN'  statement]  To  hand 
  off  execution  to  a  child  or  successor  without  going  through  the  {OS} 
  command  interpreter  that  invoked  it  The  state  of  the  parent  program 
  is  lost  and  there  is  no  returning  to  it  Though  this  facility  used 
  to  be  common  on  memory-limited  micros  and  is  still  widely  supported 
  for  backward  compatibility,  the  jargon  usage  is  semi-obsolescent; 
  in  particular,  most  Unix  programmers  will  think  of  this  as  an  {exec}. 
  Oppose  the  more  modern  `subshell'.  2.  n.  A  series  of  linked  data  areas 
  within  an  operating  system  or  application.  `Chain  rattling'  is  the 
  process  of  repeatedly  running  through  the  linked  data  areas  searching 
  for  one  which  is  of  interest  to  the  executing  program.  The  implication 
  is  that  there  is  a  very  large  number  of  links  on  the  chain.

  chain 
 
  1.    (From  {BASIC}'s  CHAIN"  statement)  To

  {operating  system}  {command  interpreter}  that  invoked  you

  for  all  x,y  in  S,  x  <=  y  \/  y  <=  x. 
 
  I.e.  any  two  elements  of  a  chain  are  related.

  From  Easton's  1897  Bible  Dictionary  [easton]: 
 
  Chain 
  (1.)  A  part  of  the  insignia  of  office.  A  chain  of  gold  was 
  placed  about  Joseph's  neck  (Gen.  41:42);  and  one  was  promised  to 
  Daniel  (5:7).  It  is  used  as  a  symbol  of  sovereignty  (Ezek. 
  16:11).  The  breast-plate  of  the  high-priest  was  fastened  to  the 
  ephod  by  golden  chains  (Ex.  39:17,  21). 
 
  (2.)  It  was  used  as  an  ornament  (Prov.  1:9;  Cant.  1:10).  The 
  Midianites  adorned  the  necks  of  their  camels  with  chains  (Judg. 
  8:21,  26). 
 
  (3.)  Chains  were  also  used  as  fetters  wherewith  prisoners  were 
  bound  (Judg.  16:21;  2  Sam.  3:34;  2  Kings  25:7;  Jer.  39:7).  Paul 
  was  in  this  manner  bound  to  a  Roman  soldier  (Acts  28:20;  Eph. 
  6:20;  2  Tim.  1:16).  Sometimes  for  the  sake  of  greater  security, 
  the  prisoner  was  attached  by  two  chains  to  two  soldiers,  as  in 
  the  case  of  Peter  (Acts  12:6).
