ISAM 10/29/80 ISAM NAME isam - generate index for pseudo-indexed-sequential access SYNOPSIS isam [-d] [-w] [-j] 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.
