Reading magnetic strip card

[Louis BROUILLETTE]

Chris,

That helps to skip the semicolon but I need the rest of the string.  How
would I do this ?

If I can't find anything else, I think the best solution would be to add a
designer procedure to change the separator character from ";" to something
else so the user would decide to do it if he has a magnetic strip reader.

Thanks everyone for your help.
