This function decodes a base 64 string into a BLOB (Binary Large Object). It returns the number of bytes written to the BLOB. An error 26 is displayed if the input is invalid.

Syntax

LENGTH=B64Decode(SOURCE_CLOB, DEST_BLOB)
  • DEST_BLOB has type Blbfile.
  • CLOB_SOURCE has type Clbfile or Char.
  • LENGTH has type Integer.

Examples

# Decode a base 64 CLOB into a BLOB
# If an error occurs, return -1
Funprog DECODE(SOURCE, DESTINATION)
Const Clbfile SOURCE
Variable BlbFile DESTINATION
Local Integer I
  Onerrgo ERROR_FOUND
  I=B64Decode(SOURCE,DESTINATION)
  End I
