I think I would take it and always convert it down to one format

lc_data = "9999-99-999-9999"
lc_data = STRTRAN(lc_data, '-')
lc_data = PADR(lc_data, 13, '0')
lc_data = TRANSFORM(lc_data, '@R 9999-99-999-9999')

Of course you could combine multiple steps into one. But this is the way I would go about it. The STRTRAN won't do anyting for one's that don't contain a dash but atleast the data will be formated the same way each time.
