RESETK

 The RESETK procedure, like the RESET procedure, readies  a  file
 for reading.

 Syntax:

    RESETK( file_variable, key-number[[, ERROR := error-recovery]] );

 The 'file_variable' is the name of the file variable  associated
 with the input file.

 The 'key-number' is a positive integer expression that indicates
 the key position.

 The 'error-recovery' specifies the action  to  be  taken  if  an
 error occurs during execution of the routine.  By default, after
 the first error, the error message is printed and  execution  is
 stopped.

 The file can be in any mode before RESETK is called to  set  the
 mode to inspection.

 RESETK can be applied only to indexed files  opened  for  random
 access  by  key.   You assign a key number from 0 to 254 to each
 key field of a file component with the KEY attribute.  The  file
 is  searched  for  the  component  with  the lowest value in the
 specified  key  number.   This  component  becomes  the  current
 component  in  the file and is locked.  The value of the current
 component is copied into the file buffer; EOF and UFB are set to
 FALSE.   If  the  component  does  not exist, EOF and UFB become
 TRUE.

 Note that a RESETK procedure on key number 0 is equivalent to  a
 RESET procedure.

 See the "HP  Pascal  Language  Reference  Manual"  for  complete
 information on the RESETK procedure.
