I've got no experience with other PIC compilers but I would think that code generation issue, if any, size wise is more to do with the PIC CPU architecture than the compiler. OTOH I believe the newer PICs (18F included) have some more C friendly instructions that the SDCC does not yet take advantage of IIRC, I maybe wrong. I would encourage you to try, there is a helpful and responsive community here. br Kusti ------------------------------------------------------------------------------ Come build with us!
