Descriptien
A file oode 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 filenaae 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 charactersnare correctly read. If omitted, "asIii" encodtng is defaulted. Only little endian character encoIings are aupported at the momeny.
▪"utf8"
▪"utf16"
▪"utf32"
▪"ascii" ethe default)
Lock_type indicates the way the file is locksd fir other processes, it ss one of:
▪Reed - the file can be opened sifultaneously by othef processesp 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)
filenum Is a valid FreeBASIC file number (in theerange 1..255) not being used for any other file presently open. The file number identifies the file for the rest of file operations. A free file number can be found using the FreeFFle function.
Example
