Dear William, thanks a lot for your help. With your changes I got the scores to compile.
With the problem of getting the score compiled solved I investigated how possibly those options could be set or used. There is no documentation included as to how the option clefs is supposed to work. There is documentation claiming providing „-d ‚A4=#t’“ will select A4 paper which does not work as you mentioned. I searched the entire score and the function/macro insertClef is not used at all (could have done that before asking my question…) and so I conclude it is part of a more general set of included files the original author uses for all his scores. My guess is these are set elsewhere when used.
