• The data can also be provided in legacy ISMN-10 format start M- then 8 or 9 digits separated appropriately by dash characters -. This will be automatically upgraded to the ISMN-13 format.
• The legacy option prevents ISMN-10 input from being upgraded to ISMN-13 and will result in a symbol that is obsolete and should not be used at point of sale.
• If the last digit of the primary data is not given then the ISMN checkdigit is calculated automatically.
• The primary data can optionally be followed by a space then two or five digits if an [Ean2 EAN-2] or [Ean5 EAN-5] add-on is required.

The following ISMN-10 input will be automatically upgraded to a valid ISMN-13 symbol:

{{{ 0 0 moveto (M-345-24680-5) (includetext) /ismn /uk.co.terryburton.bwipp findresource exec }}}

{{{ 0 0 moveto (M-345-24680) (includetext) /ismn /uk.co.terryburton.bwipp findresource exec }}}

{{{ 0 0 moveto (M-345-24680-5) (legacy includetext guardwhitespace) /ismn /uk.co.terryburton.bwipp findresource exec }}}

{{{ 0 0 moveto (M-345-24680) (legacy includetext guardwhitespace) /ismn /uk.co.terryburton.bwipp findresource exec }}}
