Control File Format
The control file is a text file consisting of one or more control instructions, one to a line:
| • | A line starting with a semicolon (;) is treated as a comment line and ignored. |
| • | Blank lines are ignored. |
| • | Each instruction line starts with a single character code (for example, U), possibly followed by a modifier (for example, +). |
| • | The code (plus optional modifier) may be followed by one or more fields separated by commas. |
| • | White space following the code character (plus optional modifier), or following a field delimiter comma is ignored. |
| • | Commas may be included in attribute values (since these are always the last field on the line). |
The maximum line length is 512 characters.
