NoteTab automatically detects the format (DOS/UNIX/Mac/Unicode) of a text file when you open it. During the loading process, UNIX and Mac files are converted to the DOS/Windows format. Through the "Options | Documents | Save As" setting, you can determine what format should be used when the document is saved. If you choose "Original", the original format is restored.
You can open and edit DOS ASCII files in NoteTab. As there is no way the program can automatically detect whether a file contains ASCII or ANSI characters, you must specify the format yourself when you open the file. By default, NoteTab assumes your files use the standard ANSI character set. See the ASCII Documents topic for more details.
NoteTab also lets you open and edit (commercial and trial versions only) EBCDIC files. As there is no way for NoteTab to automatically detect such files, you must open them by choosing a file filter in the File Open dialog box that contains the text EBCDIC. NoteTab will prompt you for a line width if it detects a fixed-width text that does not use the standard widths of 80, 132, and 133 characters; use a value of zero if you want to specify a variable-width file with line breaks.
