George:

I activated the following instructions:
*!* m.nErrCode = RegSetValueEx(THIS.nCurrentKey,m.cValueName,0,;
*!* REG_DWORD,m.cValue,m.nValueSize)

*!* m.nErrCode = RegSetValueEx(THIS.nCurrentKey,m.cValueName,0,;
*!* REG_DWORD,@m.cValue,m.nValueSize)

The value of m.nErrCode was 87 in both cases.
