Method should be overridden if needed

Overrides:

getInstructions in class Lop

Parameters:

lhsInput - input 1

rhsInput - input 2

rowl - input 3

rowu - input 4

coll - input 5

colu - input 6

output - output

Returns:

instructions as string

toString

public String toString()

Description copied from class: Lop

Method to have Lops print their state. This is for debugging purposes.
