Non-printable Hex and Decimal Values
Symbols may be inserted into map rules and component rules. Symbols may be
inserted from the Symbols dialog box or by typing the hexadecimal or decimal
value. The following lists the non-printable hexadecimal values, decimal values,
and the abbreviation for ASCII characters.
In this list, some characters in the character name are capitalized to indicate the
common abbreviation for the character. For example, the <STX> abbreviation
represents the StartofTeXt character.
The hexadecimal values are provided as a reference. For any literal Value
specified in the Type Designer Properties window, hexidecimal values must be
enclosed in double angle brackets. For example,
<<0A>> represents the
hexadecimal value for a line feed charcter.
The decimal values are provided as a reference. Decimal values may be used with
the SYMBOL function. For any literal Value specified in the Type Designer
Properties window, decimal values must be enclosed in single angle brackets. For
example, <10> represents the decimal value for a line feed character.
