How do I set the ISAMFILES runtime parameter for dL4 for Windows?

The runtime parameters are set in the Windows Registry setting keys HKEY_CURRENT_USER\Software\DynamicConcepts\dL4\Environment or HKEY_LOCAL_MACHINES\Software\DynamicConcepts\dL4\Environment.

Please refer to dL4 Installation & Configuration Guide for Windows 95/NT for details
