demo_src("") is used to displays the source code of demo program "";
whereas demo_src() displays the source code of the demo macro package itself.

local(retval,shellcmd,filename);
if (program_name.class() == "String") {
filename = getenv("MATVECHOME") + "/examples/interface/txt/";
filename += program_name;
shellcmd = PAGER + " " + filename;
retval = system(shellcmd);
}
else {
error("demo_src(program_name): program_name must be a string");
retval = 0;
}
return retval;
