NAME
       isam - generate index for pseudo-indexed-sequential access

SYNOPSIS
       isam [-d<dif>] [-w<width>] [-j<l/r>]

DESCRIPTION
       isam is used to generate an index for a text file such that the
       index  may be used later to permit indexed-sequential access to
       the file. isam reads every `dif'th line (default is 1) from the
       standard input, noting its disk address with a call  to  markl.
       It  uses  getwrd to retrieve the first "word" from the line and
       uses this as the primary key to the record.  This key  is  then
       output  to  standard output in a field `width' wide (default is
       25) and justified according to the -j  switch  (default  left).
       The  two-word  address  from  markl  is  then output as decimal
       integers before the index record is flushed.
