An engineer will have to re-work, expand an exisiting Fortran 77 code and often will (re-)learn programming in that activity by imitation of the existing code. Another reason is that the "modern" features (90+) are not very intuitive to the eye - a sort of over-verbose C syntax with contorsions to keep compatibility with Fortran 77. Would I have to program in Fortran, I would stick to the 77 syntax which is relatively simple and readable with many modern structures. It is already somewhat difficult to keep a minimal security with 77 (E.g. forgetting "implicit none", headaches with the variable visibility, "common"s & Co). For bigger or new programs, or more complex data structures the best to do is to acquire/download an Ada95 compiler and use f2a.pl to translate parts. ______________________________________________________ Gautier -- http://members.xoom.com/gdemont/gsoft.htm
