Help building a simple conditional logit model?

Hi there

I was recently asked to translate some code from Stata to SAS, and I'm all done except for the final modeling step. In this model, the dependent variable is CONSID, independent variables are ALT, RPL_:, IH_:, SW_:, x:, trend:, and ALLNEW. Additionally, there is a grouping variable CUSTOMER and a sampling weight REG_WT ("pweight" in Stata).

As someone who is new to SAS and has no real experience with these models, I'd appreciate any help! Apologies that I'm basically just asking for code - if anyone wants some help with code in R feel free to ask me hah.
