OpenMx General Help

Hi --- I was just curious if there is documentation regarding the codes in @output$status. I've been looking at [[1]], and think I have figured out the values for Code Red (6) and Green (1), but now I'm also producing values of -1 and 4. I was also curious what the values in [[2]] and [[3]] tell me, and the associated codes.

There seems to be a problem with how OpenMx and Xgrid interact. I have three machines on my Xgrid, each of which has no problem running OpenMx. After submitting jobs, the R scripts come back with the following errors:

> require(OpenMx)
