I've set the attributes parameter to position 7 so that the limited width and the overlap remain optional.

There is another way to handle default parameter values. I'm not sure if it will be better, but it doesn't require creating separate functions with different numbers of parameters. For this purpose, you can use a variable-length argument. This solution allows passing from 1 to 16 values to the function. Then it's just a matter of checking the types of the passed values, which can be done by comparing entire lists.

For example (inside the "CASE", all permissible scenarios should be listed):

Code:

EXPORT DRAWTEXT_P(...par)
BEGIN
  LOCAL pt;
  pt:=EXECON("TYPE(&1)",par);
  CASE
    IF EQ(pt,{2,8,0}) THEN
      //set params default values
    END;
    IF EQ(pt,{2,0}) THEN
      //set params default values
    END;
    IF EQ(pt,{2,8,0}) THEN
      //set params default values
    END;
    RETURN "Syntax Error";
  END;
  //The rest of the function's code 
END;

How would this work for these different types of bold, perhaps using a decimal value?

There are many possibilities here. It's a matter of preference. It could even be a string where each character corresponds to enabling a specific format, for example: B - bold, U - underline, I - italic, S - strikethrough, D - double-bold, F - framed. If any of these letters appear in the string (using INSTRING), then it's clear that a specific format needs to be set. But decimal presentation is also fine.
