Prime OS Error?

[toml_12953]

I don't know if this was caused by updating to the beta version of the OS or not but it used to work:

I have a small routine (below) that I used to call from other programs and it worked fine. Now, however, I get a syntax error when I try to call it.

Code:

EXPORT TAB()
BEGIN
  LOCAL I,T;
  T:="";
  FOR I:=1 TO X DO
    T:=T+" ";
  END;
  RETURN T;
END;

Called by:

Code:

PRINT(TAB(14));
