Offset

Specifies the register containing the offset for the protected-mode address.

Length

Specifies the register containing the length in bytes of the data to copy.

Write String (Interrupt 10h Function 0Eh) is called with the ES:BP register pair pointing to the string to print and the CX register specifying the number of bytes to display. The following script translates this function:
