Hello,Yes, if you choose a fixed length font like Courrier, the layout of the listing is left as in your text editor, with the possibility of syntax highlighting, line numbering and a lot of other possibilities. For me it works very well : I teach Fortran and I use a lot of program extracts in my documents. The only problem I had was with the trees ... they use special characters and it seems to block LyX...
