Description
Returns the substring of a specified number of bytes that appears at a specified position in a string.
MidBStr returns a substring of AByteCount bytes beginning at AByteStart bytes.
If AByteStart is larger than the length of AText in bytes, MidBStr returns an empty string.
If AByteCount specifies more bytes than are available, only the available bytes are returned.
Note: MidBStr assumes all characters are one byte-long, and does not behave correctly if AText contains multi-byte characters. To handle all strings correctly, use MidStr.
