LispWorks normally maps its heap on startup in the same place that it was when it was saved, and when it needs more memory it maps this nearby. This applies when LispWorks is a dynamic library as well as for LispWorks executables.
This mapping can cause memory clashes with other software, which may be avoided by relocating LispWorks. Most of the LispWorks implementations are relocatable though the details vary between platforms and between 32-bit LispWorks and 64-bit LispWorks.
On Microsoft Windows and Macintosh, LispWorks detects and avoids memory clashes automatically. On other platforms, you can relocate a LispWorks dynamic library (for all the relocatable implementations) if necessary by a suitable call to InitLispWorks as described in 27.6 Startup relocation.
