Re: [NTG-context] ! Declared variable conflicts with previous vardef [Metapost]

ction z := point > 3.6 of p ;) It works because of the "pair z” statement. Attempted explanation: Metapost variable names are built up hierarchically. When you say “path p” or “color V.Q” or “numeric z[]” or “vardef z”, it changes the type of just the last segment, not other segments

Re: [NTG-context] ! Declared variable conflicts with previous vardef [Metapost]

z is a MetaPost intrinsic, something along the lines of vardef z@#=(x@#,y@#) enddef; so you can't use the same name for a pair. Actually you can simply delete the declaration pair z[]; from your file and it will work as intended. If you insist on using your own declaration of z
