: After putting the definition you proposed last in front of my minimal example in mkiv beta 2015.02.03 it worked once and then not any more. I also tried to remove all auxiliary files after a new pass.
But today I installed beta 2015.03.10 (complete fresh install as I keep the older version in a renamed folder) and now the MWE with your extra code renders repeatedly correct.
So this seems to be a workaround until you rewrite “write” as you said.
I will experiment further with tikz’ ‘remember’ picture mode.
1. The current beta has a fix for the \write command and you don’t need Hans patch. 2. Commands with a _ in the name, e.g. \syst_write can only be used when you place them in a group which starts with \unprotect and ends with \protect. Wolfgang
