Robert - did you turn off debug information when you determined the size of the .exe files? that may be a big part of why TC++'s .exe files are so large. if you have the professional package or a copy of our Turbo Debugger product you can use the TDSTRIP.EXE utility to get rid of the debug info without having to relink. Turbo C++ is both an ANSI C and C++ 2.0 native code compiler. In order to pack the compiler into the 640k of DOS we use our VROOMM technology to dynamically load code segments on demand. If you have expanded (EMS) or extended (EMM) memory the compile times can be improved. if you use the programmers platform specify the command line switches /e and/or /x (you can also use the TCINST program to set those options up). the compiler will use both types of memory to cache the code segments of the compiler. If you use the command line compiler specify -Qe (for expanded memory) and -Qx (for extended memory) to have the compiler cache its code segments. Also for anyone reading this message, if you are going to compare sizes of generated .obj files - you have to look into the object file itself to see how much code and data was generated. There are lots of comment records in the .obj file for debugging, path and timestamp of all header files (autodependencies) used, and other information for the linker. You can use our TDUMP.EXE utility that comes with the professional package or the debugger and tools product to dump out the sizes of code segments and data segments for .obj and .exe files.
