Orman. It combines multiple small [[DOS executable (.com)|COM]] files into a single &quot;library&quot; COM file. The user can then execute the library file, with a command-line argument to tell it which of the original files to execute.<br /> <br /> Extraction and execution of the original file is apparently done all in memory. COM-Pack doesn't seem to provide a way to recover the original files from a library.<br /> <br /> == Identification ==<br /> Library files are observed to start with bytes {{magic|e9 46 01}}, followed by text that begins {{magic|0a 0d 20 20 43 4f 4d 2d 50 61 63 6b}} (&quot;{{magic|\n\r&amp;nbsp;&amp;nbsp;COM-Pack}}&quot;...).<br /> <br /> == Software ==<br /> * {{CdTextfiles|swinnund/disk3/FILEUTIL/COM_PACK.ZIP|COM-Pack}} (ambiguous version number: 1.0 or 1.1)</div>
