How do I perform a Cox proportional hazard analysis?

In Sweden I seem to be the only person who uses the excellent statistical software JMP. I have used it for several years and now have version 14.2.0. The majority of the research colleagues that I work with use SPSS but I think JMP is much better. However, since I am a surgeon my statistical knowledge is somewhat limited. I know JMP fairly well but I mostly do univariate and multivariate analyses of nominal data. However, now I got a question from a journal regarding the Cox proportional hazard analysis of the data. Since I do not know how to do that in JMP I would appreciate if the community could help me. The dependent (y) variabel is continuous and is time to event (in bold, see a small sample below). To the left (in italic and book antiqua) are the x variables as nominal values and to the right of the y variabel are the x variables converted to numerical (1 or 0) values where 1 is a "positive event" and 0 is the reference.

I wonder how I do in JMP to get the results of these sample data (these are just examples and not the real data) and I would like to be able to present it like below. I would prefer an instruction of how to do it in an interactive mode. However, if possible also in a scripting answer. My knowledge of how to use JMP regarding programming is somewhat better than my statistical knowledge.

Of JSL code I have no knowledge.

Cox Proportional Hazards Model is available under the Fit Model Platform.  Here is a link to the JMP Help on it.
