    Hello everybody,

    I have a few problems with following code (see screenshots):

    • First problem: I define a new symbol replacement directive, but the compiler doesn't recognize the defined symbol "REPLACE_ME" after the pre-compiler has build it.
      And he definitly pre-compiles this piece of code since I can see in the output that debug mode is enabled !
      Does anybody know how to use the {define identifier string} macro ?

    • Further more I want to write my own ASSERT(x) macro which is only defined during debug mode, and wich takes 1 or 2 parameters for validation.
      Second problem: you can't define DEBUG outside PLC_PRG. I found this issue back in the help and I think this is a major limitation! How would it be possible to use my ASSERT(x) macro in other libraries??
      Third problem: It's not possible to use the symbol " {error '...'} " inside a {define identifier}. How can I display an error in the output?
      Fourth problem: in C++ you can convert x to a string using #, but how is this done in CoDeSys?
      Fifth problem: how can you define the identifier as a function, which takes 1 or more parameters?

    Thanks for all help and comments !
