In the case of that library it is actually buried in the .h and .cpp files themselves.  Version 1.1 is wat I found in those files.  I have never used the library you point out, but the one that was originally used for the video Bill produced.  That library has been relocated to GitHub at:  New-LiquidCrystal Library

Thank you very much codecage.  I cleared my library of existing liquidCrystalI2c libraries and went to GitHub downloaded  the zip file, and lo and behold it worked. The LCD_liquidCrystal_demo  2018  now verifies

I have reviewed the  original video "Using LCD Displays with Arduino" and in it Bill does say to use the NewLiquidCrystal library for I2C  from github.com  If I had done this in the first place I would not have had all this trouble. I do not know where the LiquidCrystal library that I had installed came from but it worked on other projects so I assumed it to be ok. I have an existing stop watch that uses the library it is fine as the program  does not contain  that "POSITIVE" command.

I was determined to succeed after devoting so much time to it, but I still do not know exactly what the "POSITIVE" command does. The same command also appears in the Temperature & Humidity Gauge sketch.

If I remember correctly it controls whether the back light is on or not.
