Escape sequences

The less-than sign (<) is a reserved character. To use this character in a string, you must either enclose the whole string within escape sequences <[ and ]>, or use the ASCII code for the < character.

Examples

Example 31

Escaping the < character using <[ and ]> escape sequences

$select_2 = "<[Select list.questions from list 
where list.id < ]>" + $num;

If $num=2, this gives the following result:

Select list.questions from list where list.id < 2;

 

Example 32

Escaping the < character using the ASCII code for the < character

$select_2 = "Select list.questions from list 
where list.id <3c>" + $num;

If $num=2, this gives the same result as above:

Select list.questions from list where list.id < 2;

 

Example 33

Using the Log function to append a string containing a < character to the log file

Log (0, "<[Value < 5]>");
