Hexadecimal values

A hexadecimal value is a constant made up of a combination of the hexadecimal digits A through F and 0 through 9.

All character strings except names, dates, and times can be specified in hexadecimal form. To specify a hexadecimal value, the digits must be specified in multiples of two, be enclosed in apostrophes, and be preceded by an X. Examples are: X'F6' and X'A3FE'.

Note: Care should be used when entering hexadecimal values in the range of 00 through 3F, or the value FF. If these characters are shown or printed, they may be treated as device control characters producing unpredictable results.
