If record1 is GE Min-num and LE Max-num
Calculate total.



assume that record1 has a value 'A' and now in this case what will happen for the above comparision???? what will be min-num ,max num and will total be calulated

Min-num = X'00'
A = X'C1'
Max-num = X'FF'

Min-num = X'40'
A = X'C1'
Max-num = X'40'

"total" will only be calculated when record1 contains a space......
