TOBASE64$ Function

string$ = TOBASE64$(address, length)

The TOBASE64$ function encodes binary data from a memory buffer into a Base64 ASCII string.

This is useful for safely storing or transmitting binary data in text form, such as network payloads, file contents, or encoded assets.

---

Parameters

• address Source memory address containing the binary data.
• length Number of bytes to encode.

---

Return value

Returns a Base64 encoded string. Returns an empty string if length is 0 or an error occurs

---

Example

buf = MEMALLOC(10)
 
FOR i = 0 TO 9
    POKE buf + i, i
NEXT
 
b64$ = TOBASE64$(buf, 10)
 
PRINT b64$

This encodes 10 bytes from memory into a Base64 string.

Notes

• The output is standard RFC 4648 Base64.
• The returned string is always ASCII text.
• Binary data can be restored using FROMBASE64.
• The output string is larger than the source data.
