I created a subdirectory on a Windows (Vista) box and placed the following files in it: ape.exe <a href="http://clex_lexicon_2000_words.pl">clex_lexicon_2000_words.pl</a> (a renamed copy of the ~2000 word lexicon included with the AJP) <a href="http://clex_lexicon_100000_words.pl">clex_lexicon_100000_words.pl</a> (a renamed copy of the ~100000 word lexicon made availability on Attempto's download page) test_program.ace (a file that contained some ACE sentences) generate_test_ACE_DRS_XML.bat (a Windows batch file I created) generate_test_ACE_DRS_XML.bat contained the following two lines: ape -ulexfile <a href="http://clex_lexicon_2000_words.pl">clex_lexicon_2000_words.pl</a> -file test_program.ace -solo drsxml > test_program_2000_word_lexicon.ace.drs.xml ape -ulexfile <a href="http://clex_lexicon_100000_words.pl">clex_lexicon_100000_words.pl</a> -file test_program.acee -solo drsxml > test_program_100000_word_lexicon.ace.drs.xml When I ran the batch file it created a file named "test_program_2000_word_lexicon.ace.drs.xml" and a file named "test_program_100000_word_lexicon.ace.drs.xml". test_program_2000_word_lexicon.ace.drs.xml contained the ACE sentences in the test_program.ace expressed as ACE DRS XML, as expected, but test_program_100000_word_lexicon.ace.drs.xml was empty. No error messages were displayed in the Windows Command Window I used to execute the batch file. I downloaded the Large Content Word Lexicon (Clex) a second time in case the file had been corrupted during the download process, but that didn't fix the problem. Any ideas what may be causing this problem? Thanks, -- Ken
