I am getting many errors off of a compile/link attempt from code from Cygnal. The first one is a L107 on the bit area. Segment ?BI?SMB_EX3. This is the result of going to: http://www.cygnal.com/support/applications.htm downloading the code in AN013SW, and using the SMB_ex1.asm file and the SMB_ex03.c file. I get this message even if the startup file is not part of the project. I have emailed their forum, but some of this seems to be more your problem (L107 as an example). There were other errors after that one, but I read that the first error should be considered first. Seanearlyaub@hotmail.com
