AppendToFile(FileName, Content)

AppendToFile will add a string at the end of a file.
If the file did not exist, it is created.
The path indicated should be constructed according to your platform.
Windows/DOS way: c:\texts\accounts\year98.txt
Unix way: /texts/accounts/year98.txt
Note the different slashes...

AppendToFile does not understant the ftp:// type, but SavFile (in the internet family) does.

Return Value:
Number of bytes written.
If the value is different from the length of the string you specified, then check the _errno variable for details.

Example:
The file myfile.txt aready contains:

Hello world
-----------

appendToFile("myfile.txt","\nthird line")

Hello world
-----------
third line

Notes
Using AppendToFile heavily is not recommended when good performances are required.
Rather, it is better to work on a variable, append content to it and then use SaveFile.
