• Description:
    Header (resp. startup file) is a piece of code what is run at the beginning of the executable. It usually makes some variable initiallisations, library opening etc. Each header should call function called 'main()'. It is usually written in assembler to get the best perfomance, but it can be written in PowerD as good.

    Some example startup codes are in 'd:lib' directory.

  • Header module:
    If you wrote a header, you should write also a module what contains in the header initialised but external variables (via 'EDEF') and OPT HEAD='xxx.o' where xxx is the header object file name in 'd:lib', or '*' and full path.

  • Example: 
      OPT HEAD='startup_tri.o'
