-a - Disables UTF-8 encoding of characters in the range 0-255, as long as the text contains no characters > 255.
-c - Chops the file at the end of the copied bytes.

Parameters

<filename> - File to modify.
<S> - Byte position in the file to start writing to. (zero based)
[N] - Byte count from <text|%var|&binvar> to write.
<text|%var|&binvar> - Text/%variable/&binvar to write to file.

Example

alias example {
  ;Write some text to a file at beginning of the file
  /bwrite file.txt 0 hello there!

  ;Read the binary data into binary variable &tempfile
  /bread $qt(file.txt) 0 $file(file.txt).size &tempfile

  ;Print the binary variable data as text, outputs 'Hello there!'
  echo -ag $bvar(&tempfile, 1-).text

  ;Replace "there!" with "world!" 
  /bwrite file.txt 6 world!

  ;Read the binary data into binary variable &tempfile
