We have a number of csv files. Below is one of them:

CODE,DT,OP,CL
600038,2023-06-02,4.39,4.5
603818,2023-06-02,215.93,235

Use Java to do the task: Use file name as the parameter and read the last line of the csv file.
Here is the SPL code:

=file(?).read@n().m(-1)

read@n()function reads each text file line by line. m(-1) function gets the last member of a sequence.
