What are "SAS codes"?  Do you mean two SAS programs?  If so then they are text files, and there are numerous ways to compare text files.  You could read both in via file statements in datastep, then compare them as a series of observations with text.  You could look at third party text compare tools like textdiff.  You could utilize the version control software that you do have - right? - SVN for instance can provide text file comparisons.  

At the end of the day, the comparison is just between text though, if there is a new row high up in the program then that pushes the rest of the check out.  What you may want is more of a key identifier merge - i.e. lines of code which match or are similar and use those for positional matching, e.g
original

abc

def

ghi

 

new

abc

ert

def

ghi

 

Textually matching means on the first obs matches, pattern merging however would match 3 out of 4.
