You can optionally have DrawMerge Zero-pad the numbers it generates to any number of places.
Unpadded numbers look like this:
1
2
3
000001
000002
000003
Zero-padding can help you solve text alignment problems in your output. By applying zero-padding, you ensure that all of the numbers output by DrawMerge will be the same width.
Note that DrawMerge will not let you specify zero-padding to fewer places than the number of places in the number in the To field. For example, if you enter To: 1000 DrawMerge won't accept a zero-padding value of less than 4, since there are 4 places in 1000.
You can, of course, specify more places than that.
