**By using line numbers, MX is able to identify which line has been deleted or edited ignoring the date (although unlike Cumulus 1, MX does not allow you to change a date) | |||
**Cumulus 1 does not actually number lines, it counts lines as it reads them, so if there is an error when it reads the file, the original Cumulus will report the line number where it first found an error. | |||
*The original table below was for Cumulus 1 and then field number '''was''' starting from zero. So in some forum posts you might see references to old numbering, in others to new numbering.

*# | *#Cumulus 1 stressed that the date field was different to the rest, as it was used as identifier. The date '''must''' be a unique identifier, the same date should not be repeated in another line, however Cumulus 1's editor allows you to change that date field. | ||

**Numbering starting from zero is consistent with standard indexing used for arrays in programming languages (like JavaScript), so the number shown '''was''' the number to quote in any scripts where a line was converted to an array, and you needed to address a single field. | **Numbering starting from zero is consistent with standard indexing used for arrays in programming languages (like JavaScript), so the number shown '''was''' the number to quote in any scripts where a line was converted to an array, and you needed to address a single field. | ||
