> FORTAN I have not thought of FORTAN as legacy because whenever I need to look at very old FORTRAN code I am looking at mathematical structures such as matrices and vectors. At that point I am not thinking of FORTRAN anymore but another language (such as linear algebra) which is few hundred years old but still so crisp in a world of numerical computing. HOWEVER: I cannot say the same about ABAP or Java that initially began to take shape in an enterprise system 20 years back. Then I have to go through reams of code that is truly legacy, hard to navigate through years of modifications, dependent heavily on local contexts, personal perferences, etc.
