There are microcodes in .inc format out in the wild which contains lines with just a comment. So these files look like the following example: ; External header dd 000000001h dd 00000001bh ... ; Data dd 000000000h ... The lines with just a comment starts with a ';' and will break the current awk formatting which is performed to reformat the content into C code style. As we are just interested in the data we can simply drop all lines that start with a ';' which sed can do pretty easy.
