[AMOS] - Was AMOS 4.01 able to handle endogenous categorical variables?

#1
I’m making my masters thesis and trying to replicate path model study that was made with AMOS 4.01. I can't find AMOS 4 user manual. I get similar results when I handle categorical variables as continuous. I’m wondering if the original analysis got good model fit because they didn’t handle categorical variables correctly.
