[basex-talk] Standalone RUN for .bxs file not working in version 8.4

Hi, I'm unable to use RUN in standalone mode in BaseX 8.4, including the latest downloadable snapshot dated yesterday. The same thing in BaseX 8.3 works fine. java -cp BaseX842-20160310.184258.jar org.basex.BaseX C:/Users/username/.basex: writing new configuration file. BaseX 8.4.2 beta 9b9f74a [Standalone] Try 'help' to get more information.

RUN blah.bxs Stopped at ., 1/20: [XPST0003] Incomplete expression.

The reference to "1/20" comes up no matter which .bxs file I try to run, even if line 1 is a comment. Did I miss a deliberate change in configuration or syntax? Thanks, Amanda
