[AccessD] String - strip off leading zeros

Good Morning,

Does anyone have a quick function for stripping off leading zeros on a
string.  I am working with product codes, getting data from different
sources, some use leading zeros - anywhere from 1 to 5.  So, depending on
which source the data came from, the same product code could be represented
as 

1234ABC
01234ABC
001234ABC
0001234ABC
etc.

Thanks in advance,

Jennifer
