Is it possible to use macros in the Script Editor, and if so, how?

[ambalboa]

I've been reading the manual and if I understand it correctly, I cannot reference any macros to use their value. Is this correct? If not, how do you call a macro? I am trying to use the FAILSTEP_NAME macro, among others on the step tab in the script editor. So far, I am just not able to. I am following what I did on the 'Run Script' action steps but that doesn't work. Thank you in advance.
