Yeap, except i was just working with someone elses choice. Bigmatrix code uses dput() to dump desc file of filebacked matrices. I got some time to do a little hack of reading big matrices nicely to java and was looking to some ways of smoothing the edges of parsing .desc file a little. I guess i am ok now with parsing .desc with some regex. One thing i am still wondering about is whether i really need to convert back and forth between liitle endian and big endian. Namely, java platform has little endian native byte order, and big matrix code writes stuff in big endian. It'd be nice if i could manipulate that by some #define somewhere in the makefile or something and make C++ write little endian without byte swapping every time i need to communicate with big matrix from java. Thanks

Andre
