test1 basic program

The program below is sort of test code for different aspects of flexbasic. I try to work this thing in small pieces of code, so I can, hopefully find the bug, if one occurs.
Below I am having problems with the startlog/stoplog commands. It shows an error of 'u9fs', not sure what that is referencing.

Comments
I found one major problem, at least as it concerns my program. In the snippet of code, it seems that there is a problem between the COG that is started and the main program. It looks like they both start up, but are frozen to a stop. Are the two COGs fighting for dominance, and neither one is winning?
I guess I might be missing some additional code, but not sure what that would be.

Use only the cog that executed "mount".
