false:
  put char 1 to -1 of ("09114"&"e"&"715806") =  \
         char 1 to -1 of ("09114e7"&"15806")

true:
  put char 1 to -1 of ("09114"&"eA"&"715806") =  \
         char 1 to -1 of ("09114eA7"&"15806")

Also true:
put "09114e715806"&null =  "09114e715806"&null

Looks like another case where appending null is an answer to workaround
xtalk oddities where one programmers feature is another's gotcha.

Another example of a good use of Null

repeat with x = 1 to the number of lines in (fld havingEmptyLastLine & null)
put the number of items of (gInventory & null) into maxCount
