[Mesa-users] Help:Regarding extras routine error

[ABHIJNAN KAR 20064]

Also the star/others/other_wind it self states '! procedure pointer: s% other_wind => my_routine’ .I did exactly this in my extras as far as pointer is concerned but the error is coming out at the pointer position as per the screenshot attached before.

As you can see, yours is missing the input variables X, Y, and Z. This should explain the error you are receiving.
