encode-url URL-encodes <string> and stores the result in <encoded string>.
<length> in "input-length" clause lets you specify the number of bytes in <string> that will be encoded - if not specified or negative, it is the string length.
All bytes except alphanumeric and those from "-._~" (i.e. dash, dot, underscore and tilde) are encoded.
Examples
In this example, a string "str" is URL encoded and the result is in a "result" string variable:
set-string str=" x=y?z& " encode-url str to result
