STRING Help?

[toml_12953]

I'm trying to use the STRING function to print a monospaced string. I've read the manual over and over. It could really use more examples! When I try the following, I get Invalid input but I can't see what's wrong. I don't want anything fancy, I just want to print using the current parameters except in a monospaced font. Can someone point me in the right direction?

Code:

EXPORT Monospace(X)
BEGIN
  PRINT(STRING(X,0,-1,-1,{50,10,0,0,1}));
END;
