  - Funtions B
    - base64Decode()
      Decodes base64 encoded data.
    - base64Encode()
      Encodes data in the base64 encoding.
    - baseName()
      The function returns the last part of a file path.
    - beep()
      Issues a beep.
    - bitmapEditor() - obsolete
      This function opens the bitmap editor. To be able to use the function, the PVSSBitmapEditor.dll has to exist in the directory <version_path>/bin (obsolete from version 3.5 up).
    - blobAppendValue()
      Works like blobSetValue(), but the value is appended to the blob.
    - blobGetValue()
      Reads "value" from byte offset "offset" with "len" bytes from blob.
    - bloblen()
      The function returns the length of a blob in bytes.
    - blobRead()
      The function blobRead() reads the content of a file into a blob variable.
    - blobSetValue()
      Writes "value" from byte position "offset" with "len" bytes to the blob.
    - blobWrite()
      The function blobWrite writes the content of a blob variable into a file.
    - blobZero()
      Sets blob length to len bytes and initialize the blob with "0".
    - byteSizeToString()
      Converts a filesize in bytes to a string (for example, with getFileSize()).

- CTRL Debugger
  You can use the CTRL debugger to debug the Control programming language. The debugger can be used via its own panel, which also enables the monitoring and setting of variable values during the execution of a script.

beep()

Issues a beep.

Synopsis

int beep([int frequency[, int duration]]);

Parameters


Parameter	Meaning
frequency	Frequency [Hz]
duration	Duration [msec]

Return Value

Always 0

Description

Issues a beep of the frequency <frequency> [Hz] with the duration <duration> [msec]. The beep does not block program execution (own thread). Standard values are 500 for frequency and 200 for duration.

Example

{
  beep(400,250);
// Issues a beep
