  • IsEmpty() will give 1 for range out of bound. E.g. column A has text in 1st 4 rows only. In column B, enter formula IsEmpty(A) for rows from 1 to 10. row 5-10 will be filled with 1.
  • When concatenating two string columns, use longest data to set the range. E.g. if there are 5 rows of data in column A, while 10 rows of data in column B. Set column C's formula as A$+B$.  Origin uses the 1st vector to decide the calculation range so only 1st 5 rows was conconcated. Origin 2019b, usea the longest rwo to decide range. To go back to old behavior, which used the first vector i2, set @VAS=0
