in thread print datafields separated by tab

Hi davido,

This is wrong in (at least) 2 regards. Firstly, the syntax is wrong in the while loop. What you needed was

while (my $line = <STDIN> ) {

Secondly, chomp does not return what you think it does. It returns the number of characters it removes, in your case 1 for each iteration. So your final result will be like

1    1    1

Hope this helps

    Wiping sleepy sand out of eyes..... Thanks for the head's up. I've fixed what should have been simple code. That will teach me to cut the 'test it first' corner. ;)

    By the way, you can see my use of chomp's seldom-used return value here: Chomped JAPH.

    Thanks again.

[Discipulus]: these opcodes mentioned in the wiki pages are the same opcode perl is translated into? or is just the same term but in different fields?
