... Open for append, will write data to the end of the file. If the file does not exist, ● it will be created. ALFAT has 16 available file handles. Each file, once opened, must be associated with a handle. Closing the file, would free up the file handle. Note 1: ALFAT can access unlimited number of files. The limitation is 16 simultaneous opened files but a handle can be closed then used to open any other file ...
