Converts a buffer to a mnemonic phrase using the BIP39 algorithm.
diffApply (Function)
Applies a difference buffer to a specific buffer.
Right (Function)
Extracts the last characters from a string or string buffer.
BufferToInteger (Function)
Extracts an integer from a binary buffer at a given position.
Middle (Function)
Extracts:
  • a substring from a string starting at a specified position.
  • part of a buffer starting at a specified position.
BufferToReal (Function)
Extracts a real from a binary buffer at a given position.
Encode (Function)
Encodes a character string or a buffer. To decode the result, simply use Decode.

fIsImage (Function)
Determines whether a file on disk or in a buffer corresponds to an image format recognized by WINDEV or WEBDEV.
<DiskFile variable>.Find (Function)
Finds a character string or a buffer in a file opened by fOpen.
Decode (Function)
Decodes a character string that was encoded by Encode.
fFind (Function)
Finds a character string or a buffer in a file opened by fOpen.
fSaveBuffer (Function)
Creates and fills a text file with the content of a string or buffer variable.
