The Basics

The URLENCODE function encodes characters that might otherwise be significant when used in a URL. This function encodes all characters except for the following:

• all alphanumeric characters

• dollar sign ($)

• hyphen (-)

• underscore ( _ )

• at sign (@)

• period (.)

• exclamation point (!)

• asterisk (*)

• open parenthesis ( ( )and close parenthesis ( ) )

• comma (,).

Note:   The encoded string might be longer than the original string. Ensure that you consider the additional length when you use this function.   

x1=urlencode ('abc def');
put x1;

  
abc%20def

x2=urlencode ('why?');
put x2;

  
why%3F

x3=urlencode ('ABC#1');
put x3;
