I now have a .pbc with loadlibs and dlfuncs for pretty much the entire Win32 API. The next thing I want to look at is constants. At first I thought I could do something like:- .constant MB_YESNOCANCEL 3 But when I compile the pasm file containing that to a .pbc to use with load_bytecode, these constants appear to just get dropped. I've determined this through grepping the .pbc for the identifier associated with the constant (nothing found), and also by observing that no matter how many .constant lines I have in the source .pasm file, the size of the resultant .pbc is the same. So, is .constant not working correctly, or (more likely) not the Right Thing to use in this situation? How should I go about storing the constants for use with the APIs? Thank you, Jonathan
