Cause

---

This problem occurs because the compiler environment is not set up correctly.

---

Action

---

There are a couple of options for resolving this problem.

The quickest way to resolve the problem is to invoke the compiler from the DOS window you used to generate the code.  This will ensure that the same environment settings are propogated to the compiler.

Another option is to update your environment settings via the control panel.  Setting your environment variables to mirror the settings you have in the active DOS window that was used to generate the code.
