question on right function

[#1]

Trying to use Right function as below in my jsl code

dt << New Column("ORIG_MARK",Character,Nominal,Formula(Right(:result,(Contains(:result,"_",3)))));

The result of this statement is as below,but I intend to eliminate the "_" from every row in the ORIG_MARK column.How can I modify the above statement to accomplish this?

result	ORIG_MARK
ORIG_MARK_A	_A
ORIG_MARK_B	_B
ORIG_MARK_C	_C
ORIG_MARK_D	_D
ORIG_MARK_E	_E

Right(str, n) will return you right n characters of str. Contains(str, pattern, n) will return you first index of pattern in str starting from n. If you want to get string after last "_" I would use Word() or Substitute() to remove "ORIG_MARK_". If you want to use Right(), you will have to calculate the length of string you want get for example by using combination of Length() and Contains().

Here is one option using Word():

Word(-1, :result, "_")
