I would like to take a column with a string in it, and in each row, replace the third character from the left with a "9." How might I go about this using JSL?
Here is the simple script
Names Default To Here( 1 ); dt = Current Data Table(); For Each Row( dt:YourColumn = Substr( dt:YourColumn, 1, Length( dt:YourColumn ) - 4 ) || "9" || Right( dt:YourColumn, -2 ) );
I strongly suggest that you take the time to read the Scripting Guide, so that you will have the background knowledge that will allow you to solve these questions
