Many string settings in WTC use special characters. Examples are the use of '~' at the beginning of path strings to denote the WTC installation folder, and the use of @%' to enclose system environment variable names.

If you want to use a special character literally in a string setting, you need to "embed" it. This is done by enclosing its decimal ASCII value in angle brackets ("< >"). The entire substring, including the angle brackets, is replaced by the character value of the enclosed number in the parent string.

For example:

"C<97>t"

is the same as "cat", because 97 is the decimal ASCII value of lower case 'a'.

This method can also be used to include carriage returns and other non-printing symbols in string settings.

If the contents of the angle brackets does not evaluate to a number, an ASCII 0 is embedded, which in general will mean that it is ignored along with any ensuing characters in the settings string.

Note that string settings that are processed for embedded character translation cannot include a literal left angle bracket in their specification. The left angle bracket itself must be embedded. The right angle bracket can be included literally in a string, however.
