Re^3: Sort questions

wube,

Is there a way to delineate the end of data block, something line __ENDOFDATA__ ( if it exists )?
I was thinking more in terms of packing or caching the sort keys, but now I really don't think that's necessary. The file only contains about 400 lines

Cheers - L~R

I used __DATA__ because I assumed you were getting the data to populate the array from an external file. In this case, you would only need to open a filehandle for that file and replace the <DATA> with <FILEHANDLE>. You are absolutely correct. The final program will read input from an external file. But for testing purposes, I only wanted a subset. __DATA__ is a more elegant way of reading input data. Off course, being a newbie to Perl, I ended the data block with a blank line which set me off chasing shadows. Anyway, I finally realised what was causing the problem which led me to ask the __ENDofDATA__ question. The Schwartzian Transform is a very slick way of sorting. I like it. Sure glad you pointed it out. Thanks. wube	[reply]
