In the case of array based solution it's better to start with the item from the first row

lnMax = MyArray[1,2]
FOR lnFor = 2 TO ALEN(MyArray,1)
    lnMax = MAX(lnMax, MyArray[lnFor,2])
ENDIF

>>I have an array MyArray(100,5)
>>I want to search for maximum value in column 2 in MyArray
>>What is the best way to do this?
>>Thanks for your help
