Denis:
Thank you for your response. I tried the include_once and went through many trials-and-errors in trying to figure out what lines to change in the "configreal" file. Occasionally, I get an error indicating a syntax problem in the file. After many other attempts, I get simply a blank screen.
I'm guessing that the 'basepath' and the 'runTimePath' lines need to be changed, which is where I have been devoting my efforts. I was determined to figure this out on my own and then post the solution to the forum, but I am stuck.
I've always been able to use this technique in 1.92+ and earlier.
I have not been able to find this in the documentation, so if someone could point me in the right direction, I would appreciate it!
Thanks!
