Nevermind me. I didn't register the "next".

You are correct in correcting me; not every line is added. However, if, like he original problem, substrings can precede their superstrings, then your suggestion is inadequate.

Consider:
Code:
1 abcd    idx01    ijklm
2 abc    idx03    klm
3 abcd    idx05    jkl
4 cdef    idx06    ijklm
5 efgh    idx07    abcd
6 efg    idx09    abc
7 efx    idx11    abcd
8 fgh    idx12    bcd
9 fefx  blah  zabcdz

If, like the original data sample, substrings can precede their superstings, line 7 should be excluded because both its $2 and $4 are substrings of line 9. Your code won't catch that.

Again, I could be mistaken. yifangt has not been strictly comprehensive in describing the problem.

I hope my nitpicking isn't getting on your last nerve.

Alister

fst-mor(1)							      fst-mor								fst-mor(1)

NAME
fst-mor - Interactive morphological analyser and generator SYNOPSIS
fst-mor [options] file OPTIONS
-n Print multi-character symbols without the enclosing angle brackets. -h Print usage information. DESCRIPTION
fst-mor is an interactive morphological analyser and generator. The argument is the name of a file which was generated by fst-compiler (without using option -c). fst-mor reads the transducer which is stored in the argument file and prompts the user for input. Each input line is processed until the user enters "q" which ends the program. fst-mor has two modes, an analysis mode (default) and a generation mode. Entering an empty input line switches between the two modes. In order to explain what the program does in generation and analysis, consider the following transducer: a b:x c:<> d In generation mode, the program will print "axd" if the user enters "abcd" and "no result" otherwise. In other words, the program maps the left symbols to the right symbols of the transducer. In analysis mode, the program will print "abcd" if the user enters "axd" and "no result" otherwise. BUGS
No bugs are known so far. SEE ALSO
