15.61  REPEAT 

     TD:REPEAT "commands" [n] [FAST[=ON|OFF]]
This  repeats  the  specified  commands  n  times.   The  commands must be
specified as a string.  If n is omitted is assumed to be 9999.   ENDREPEAT
terminates  all  current  repeats,  while  RETURN  terminates  the current
repeat.  You may nest up to 5 repeat commands.  If FAST is specified  only
the  repeat  command  is  journaled  otherwise  each  repeat  is journaled
separately.  If you abort the repeat  with  CNTRL_C,  or  use  the  cursor
inside  a  repeat  and  it  is  in FAST mode, the journal file will not be
correct.  The lexical V_REPEAT[n] is the repeat number
NOTE:   The  command  SET  FILE  INPUT  should not be used inside a repeat
block.  The lines from the new file will not be executed until  after  the
repeat.
