FileAppend appends the contents of one file to the end
of another file. Both files must be text files.
FileAppend( filename, ! (input) scalar string expression appendname ! (input) scalar string expression )
A scalar string expression representing the file name to which you want to append the contents of the second file.
A scalar string expression representing the file name that you want to append.
The procedure returns 1 on success. If it fails, then it returns 0, and the pre-defined identifier
CurrentErrorMessagewill contain a proper error message.
If the first file (the file to which you append) does not exist, then this file will be created. The contents of the appended file will always start on a new line in the resulting file.
When appending files with different character encodings, the result is unpredictable.
