I have a form which I need to enter a mobile phone base station ID which is currently in the form of "any number of numerical characters" followed by a single alphanumeric option letter
etc. Technically any number of numeric characters should be allowed, but a safe limit would be 7 numeric characters and one alphanumeric at the right end of the ID.
Leading zeros are not an option, as this has to mesh into reports produced by another existing system which omits the leading zeros.
Short of asking users to enter spaces manually, I can't think of a way to make the input mask fill from the right instead of the left, so that I could use 9999990L
If anyone has any ideas, I'd love to hear them!
