st: eliminating hyphens in a data cell

["Ms. Marilyn Ibarra" <ibarra@uga.edu>]

I need to merge two data files by the variable FEIN (federal employer identification number).  

In one file the FEINS are all numbers (for example: 061266276).  

In the other file the FEINS have hyphens after the first two digits (for example: 06-1266276).  

Does anyone know how I can get them to look the same in both files so I can do a merge by the FEIN variable?

Thank you,
Marilyn.
