Maybe this is really easy and I'm just not finding a reference somewhere, but
I need to do some math operations on values read in with readhexstring 
and can't figure out how to turn them into integers, perform the math, 
then put the resulting integers in binary back into the string.

example 
/mystr1 1 string def
/mystr2 1 string def
/mystr3 1 string def
currentfile mystr1 readhexstring fe
currentfile mystr2 readhexstring 01
% Now how do I add the binary value of mystr1 and mystr2, then put the
% resulting value (255) into mystr3 ?

Any help would be greatly appreciated.
Thanks in advance...
