Sequential files are:
• | text-oriented, typically |
• | byte, field, or line-oriented |
• | variable length fields and lines |
• | files are opened for input or output, but not both |
• | the screen is a special sequential file; open for output on channel 0 |
• | the keyboard is a special sequential file; open for input |
• | serial ports may be accessed as sequential files |
• | output files may be created by the OPEN statement and grow automatically via PRINT |
• | the DATA statement pool acts like a sequential input file, internal to the program |
• | access is by default sequential but can be overridden using MX_FILEPOS. |
