Append
Specifies text file to be opened for append mode
filename
A file mode used with Open to open a text file for writing.
This mode is used to add text to an existing file with Print #, or comma separated values with Write#.
Text files can't be simultaneously read and written in FreeBASIC, so if both functions are required on the same file, it must be opened twice.
filename must be a string expression resulting in a legal file name in the target OS, without wildcards. The file will be sought for in the present directory, unless the filename contains a path . If the file does not exist, it is created. The pointer is set after the last character of the file.
Encoding_type indicates the Unicode Encoding of the file, so characters are correctly read. If omitted, "ascii" encoding is defaulted. Only little endian character encodings are supported at the moment.

Description
A file mode used with Open to open a text file for writing.
This mode is used to add text to an existing file with Print #, or comma separated values with Write#.
Text files can't be simultaneously read and written in FreeBASIC, so if both functions are required on the same file, it must be opened twice.
filename must be a string expression resulting in a legal file name in the target OS, without wildcards. The file will be sought for in the present directory, unless the filename contains a path . If the file does not exist, it is created. The pointer is set after the last character of the file.
Encoding_type indicates the Unicode Encoding of the file, so characters are correctly read. If omitted, "ascii" encoding is defaulted. Only little endian character encodings are supported at the moment.
- "utf8"
- "utf16"
- "utf32"
- "ascii" (the default)
- Read - the file can be opened simultaneously by other processes, but not for reading
- Write - the file can be opened simultaneously by other processes, but not for writing
- Read Write - the file cannot be opened simultaneously by other processes (the default)
Example
Dim i As Integer
For i = 1 To 10
Open "test.txt" For Append As #1
Print #1, "extending test.txt"
Close #1
Next
For i = 1 To 10
Open "test.txt" For Append As #1
Print #1, "extending test.txt"
Close #1
Next
