The /bcopy command can be used to copy any amount of bytes from one variable starting at a specific position into a second variable at a specific position. This command supports copying of overlapping buffers.

If the number of bytes to copy is -1, all bytes available will be copied over to the destination variable.

Note: The first byte starts at the position/index 1, 0 is invalid and will procudes an error.

Synopsis

/bcopy [-zc] <&dest_binvar> <des_pos> <&src_binvar> <src_pos> <numBytes>

Switches

• -z - Bytes copied from the source binary variable gets zero-filled after the copy
• -c - Truncates the destination variable to a length of <des_pos> + <numBytes>

Parameters

• <&dest_binvar> - The destination binary variable.
• <des_pos> - The position to which to copy the byte to.
• <&src_binvar> - The source binary variable.
• <src_pos> - The position from which to start copying bytes.
• <numBytes> - Number of bytes to copy (or -1 for everything).

Example

Alias Example {
  ; Create a binary variable 'example' and assign it some text
  bset -t &example 1 This is a cool test!
 
  ; Copy from 'example' from the 11th byte 10 bytes onward
  ; Zero-fill the part that was copied
  bcopy -z &example2 1 &example 11 10
 
  ; Print out &example's content (up to the first null)
  echo -a $bvar(&example, 1-).text
 
  ; Print out &example2's content
  echo -a $bvar(&example2, 1-).text 
}

The above example will output:

This is a
cool test!
