If you have all numbers, it will add a leading leading zero depending on what ":#" you have,

for ex., if single digit, ":2" adds 1 leading zero; ":3" adds 2 leading zeros...and so on.

If you have all letters, it will subtract the letter at the end depending what ":#" you have,

for ex., if "ABCDE", ":2" results in "AB"; ":3" results in "ABC" and so on.

If you have a dual position letter-number combination, the letter is replaced with a leading zero(s)

depending on what ":#" you have,

for ex., if "A1", ":2" results in "01"; ":3" results in "003"

If you have a multi-position letter-number combination, the letter(s) appears to be subtracted or replaced depending on position (left or right)

and a leading zero added depending on what ":#" you have

for ex., if "AA1", ":2" results in "01"; "if "11A", ":2" results in "011"

Its functionality seems to depend on what you have in the field, although as Lowlander suggests, ":2" was likely intended

primarily (at least maybe originally) for numbers.

Are you trying to recreate vinyl side order (A1 B2, B1 B2)?
