Problem: The call of <RxFuncAdd failed although the DLL to load is
accessible through the <LIBPATH.
Hint: For some DLLs the name of the DLL function to register (this is
the third parameter for <RxFuncAdd) is case-sensitive! This
depends on how the DLL was linked.
Use an ExeHdr tool or take a look at the DLL with a Hex-viewer to
get the proper spelling for the name of the register function.
Another cause for this error:
Maybe the DLL needs some other DLLs - these DLLs must also be
accessible through the <LIBPATH.
To check which other DLLs the DLL need, you can use the excellent
program PMDLL. or IBM's chkdll32.exe.
