I've recently been studying 68000 Assembler again, including Devpac and Assempro. My suggestion is that the source code may require an earlier or later version of Devpac, or that another Assembler, such as Argasm, may be able to assemble it. I had some errors with a German language disk of source code called "Spiele Selber Programmierung" (program games yourself), that may have been written with Assempro. They seemed to be caused by labels ending in colons, but one of these was s: , which is reserved anyway.
