Chuck, what language? Can you provide an example, I'm not seeing the 
format? Do you mean something like:

   scLeam -> sc_Leam

####
[leam at shaphan tmp]$ cat forchuck
scLeam
gaChuck


[leam at shaphan tmp]$ for line in `cat forchuck `;
   do
   echo $line | sed 's/\([a-z][a-z]\)\([a-zA-Z]*\)/\1_\2/'
   done
