(Note in the Mx examples that I did the analysis twice: First, as an MxGui draw file, and then once using the matrix input format (the "real" way). I write this once in Bentler-Weeks notation (i.e., with separate exogenous error terms) in Maruyamabig.mx, and then more compactly with implicit error terms (sling values on endogenous variables) (Maruyamasmall.mx).
