Selecting Which Code Points to Redefine in Printer Files

You can define any code point except hex 00. For a list of commonly used character sets, see the section on character codes in the manual. When you define a code point, you can do one of the following:

If you redefine an existing character, select which character to print (the existing character or the redefined character) by specifying option indicators for the DFNCHR keyword. If you select DFNCHR, the user-defined character is printed. If you do not select DFNCHR, the existing character is printed.

Note:
Output operations run faster when you define an unassigned code point. An unassigned code point avoids the reloading of code points when your program selects different DFNCHR keywords.
