When I start jw on ubuntu64 and run the following: 'a b c' =. 2!:2 '/usr/bin/perl -n -e ' "print" ' the j session vanishes.
Where can I find examples of using 2!:2? (I've tried the FindInFiles but I didnt find anything useful). In perl I can use a pipe as if were an input file - (for example): open F, 'cat inputfile | tr -d "7Z" |"; @wholefile = <F>; # the variable @wholefile will contain either 7 or Z Would I use 2!:2 to do something similar? Thanks in advance. David ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
