The _BASE64DECODE$ function decodes a Base64-encoded string back to its original binary or textual representation.
Syntax
- decodedString$ = _BASE64DECODE$(stringToDecode$)
Parameters
- stringToDecode$ is the Base64-encoded string to be decoded. It must conform to the Base64 encoding standard.
Description
- The _BASE64DECODE$ function takes a Base64-encoded string as input and returns the decoded data as a string.
- If the input string is invalid or improperly formatted for Base64, the function will return an empty string.
- It is commonly used for decoding strings that were previously encoded with _BASE64ENCODE$.
- The decoded string may contain binary data, so ensure the target string variable can handle such content if necessary.

Decoded string: Tho' much is taken, much abides; and tho' We are not now that strength which in old days Moved earth and heaven; that which we are, we are; One equal temper of heroic hearts, Made weak by time and fate, but strong in will To strive, to seek, to find, and not to yield. |
