[BUG] write to file

[Roger Eller]

I do the same if I am modifying a specific line in an existing file.
However, if I am appending to a file such as for logging, I use the before
or after modifiers in a file URL.

put "Log entry data" after URL ("file:" & specialFolderPath("documents") &
tLogFileName)
