- I don't use Ace, so I don't know how to do what you ask in Ace. HOWEVER,
- it is really pretty easy to do what you ask in the 4GL report writer, which
- is similar to, but more powerful than, the stand-alone ACE report writer.
- Maybe you can do the same thing in Ace.
-
- When using the 4GL report writer, you can output your control codes by using
- a PRINT statement. However, the 4GL compiler will not let you print certain
- control codes as constants, since it recognizes that they are special, and it
- calls them "unprintable" or "non-printing" characters (I forget the exact
- wording of the error message).
-
- The trick is to do the following:
-
- DEFINE code_on CHAR(3),
- code_off CHAR(3)
-
- LET code_on = ASCII 27, "W", ASCII 1 { example Epson print codes }
- LET code_off = ASCII 27, "W", ASCII 0
- PRINT code_on, rest_of_data, code_off
-
- Once the control codes are hidden inside the variables, the compiler doesn't
- know they are special, the printer accepts the codes, and prints as dictated.
