Beta 4 of LotusScript.doc v2 is out - get it here (lsdoc_200beta4.zip). This beta adds additional logging, makes the log output easier to read and fixes an issue where the sub/function parser would receive "empty source code" if the code contained a sub/function where all code was commented out using pings(') or %REM sections.
Update: Please remember to adjust the Java heap size. For more information see this post.
Update: If using Notes 7 beta 4 will not work. Please wait for beta 5.
