Welcome albascura,

Using 'more' will take a long time to see that the format is correct at the end of the file. I don't use 'more', but I use 'pg' to display a page at a time. So 'more' may have an option to display the end of the file, but I would do the following: 

   gunzip -c bnc.xml.gz.Z > vi.testlist     # I use 'vi.' for any temp
+ lists
   tail -100 vi.testlist | more             # Check if end of file is 
+correct
   cat vi.testlist | perl provalong.pl testlist.txt
   rm vi.testlist                           # clean-up

If it works then you can try the original, and if that doesn't work, you have at least a temporary work around until you find the specific problem.

Note: My background of AIX, '.Z' is used by the 'compress/uncompress' system commands and '.gz' is used with 'gzip/gunzip' system commands. Are you sure that the file wasn't created that way? 'compress' gets a 10% additional compression over 'gzip' and when disk drives were small, was a big deal. Today is not worth the CPU cycles.

Good Luck...Ed
