Hello, I hope someone will be able to put me straight as I seem to be missing something absolutely fundamental and probably just need someone to put me straight.
For anyone who has already helped me, I have switched to my Windows 11 machine and am running "2.24.3" and using Frescobaldi 3.3.0 I am creating txt files to use as .ly files and then wrapping them in Lilypond code. I know this means my code does not conform to the convention but my pre-processing benefits from everything being on one line and my reading of the manual and previous results lead me to believe this should not cause a problems. As a beginner, I tend to make something work and then reuse it but I don't seem able to get things to behave consistently, so I think I have overlooked something basic and no amount of cutting and pasting and research is fixing it. Here is an example: \version "2.24.3" { \mark "ON079-1a-_01" \key c\major \time 9/8 a''8 b''8 a''8 g''4 e''8 d''4 d''8 } { \mark "ON079-1a-_02" \key c\major \time 9/8 a'8 a'8 a'8 d''4 d''8 e''8 f''8 g''8 } { \mark "ON079-1a-_03" \key c\major \time 9/8 a''8 b''8 a''8 g''4 e''8 d''4 f''8 } { \mark "ON079-1a-_04" \key c\major \time 9/8 e''4 d''8 c''4 d''8 e''8 f''8 g''8 } { \mark "ON079-1-b_01" \key c\major \time 9/8 a''4 d'''8 d'''4 b''8 c'''8 c'''8 c'''8 } { \mark "ON079-1-b_02" \key c\major \time 9/8 a''4 d'''8 d'''4 d''8 e''8 f''8 g''8 } { \mark "ON079-1-b_03" \key c\major \time 9/8 a''4 d'''8 d'''4 b''8 c'''4 a''8 } { \mark "ON079-1-b_04" \key c\major \time 9/8 g''4 e''8 c''8 c''8 c''8 e''8 f''8 g''8 } { \mark "ON079-1-b_05" \key c\major \time 9/8 a''4 d'''8 d'''4 b''8 c'''4 g''8 } { \mark "ON079-1-b_06" \key c\major \time 9/8 a''4 d'''8 d'''8 d'''8 d'''8 e''8 f''8 g''8 } { \mark "ON079-1-b_07" \key c\major \time 9/8 a''8 b''8 c'''8 b''8 c'''8 d'''8 c'''8 b''8 a''8 } and another six lines Following the tutorial, I've left everything out but the basics and I get exactly what I expected on 2.24.3 (and also on Windows 8.1 with 2.22.2), namely 11 single bar expressions, each on their own line, with time signature and a marker with no error messages and th elovely green message "Completed successfully" But I want more ...... So I copy from 3.6.3 and wrap \score \layout and \midi round my opus ..... \score { … music … \layout { } \midi { } } \version "2.24.3" \score { { \mark "ON079-1a-_01" \key c\major \time 9/8 a''8 b''8 a''8 g''4 e''8 d''4 d''8 } { \mark "ON079-1a-_02" \key c\major \time 9/8 a'8 a'8 a'8 d''4 d''8 e''8 f''8 g''8 } { \mark "ON079-1a-_03" \key c\major \time 9/8 a''8 b''8 a''8 g''4 e''8 d''4 f''8 } { \mark "ON079-1a-_04" \key c\major \time 9/8 e''4 d''8 c''4 d''8 e''8 f''8 g''8 } { \mark "ON079-1-b_01" \key c\major \time 9/8 a''4 d'''8 d'''4 b''8 c'''8 c'''8 c'''8 } { \mark "ON079-1-b_02" \key c\major \time 9/8 a''4 d'''8 d'''4 d''8 e''8 f''8 g''8 } { \mark "ON079-1-b_03" \key c\major \time 9/8 a''4 d'''8 d'''4 b''8 c'''4 a''8 } { \mark "ON079-1-b_04" \key c\major \time 9/8 g''4 e''8 c''8 c''8 c''8 e''8 f''8 g''8 } { \mark "ON079-1-b_05" \key c\major \time 9/8 a''4 d'''8 d'''4 b''8 c'''4 g''8 } { \mark "ON079-1-b_06" \key c\major \time 9/8 a''4 d'''8 d'''8 d'''8 d'''8 e''8 f''8 g''8 } { \mark "ON079-1-b_07" \key c\major \time 9/8 a''8 b''8 c'''8 b''8 c'''8 d'''8 c'''8 b''8 a''8 } \layout { } \midi { } } Starting lilypond-windows.exe 2.22.2 [Untitled]...

Please, someone help me while I still have a little hair left to pull out on a later occasion :-}
