URLDECODE Function

Arguments

argument

specifies a character constant, variable, or expression.

Length of Returned Variable in a DATA Step

If the URLDECODE function returns a value to a variable that has not previously been assigned a length, then that variable is given the length of the argument.

The Basics

The URL escape syntax is used to hide characters that might otherwise be significant when used in a URL.

A URL escape sequence can be one of the following:

• a plus sign, which is replaced by a blank

• a sequence of three characters beginning with a percent sign and followed by two hexadecimal characters, which is replaced by a single character that has the specified hexadecimal value.

Operating Environment Information:   In operating environments that use EBCDIC, SAS performs an extra translation step after it recognizes an escape sequence. The specified character is assumed to be an ASCII encoding. SAS uses the transport-to-local translation table to convert this character to an EBCDIC character in operating environments that use EBCDIC. For more information see TRANTAB= System Option in SAS National Language Support (NLS): Reference Guide.
