As you can see, it shows all the DLLS loaded and and where they came from. http://www.jsoftware.com/jwiki/DavidMitchell?action=AttachFile&do=view&target=cdblist.txt On 4/1/2011 15:51, Raul Miller wrote: > So, I have a program that uses j.dll (j601). > > It gets a file name error sometimes, and I do not know why. > > How do I best find out basic information like the name of the file > which is in error, or the line of code which failed? > > Thanks, > ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
