These two data records perform the same function, however the LSEL data record allows input of time-step numbers with more than 5 digits.

(1) The initial record is the first record (starting time step number) that the user wishes to include in the output and statistical post-processing of the nodal loads.

(2) The terminal record is the last record (finishing time step number) that the user wishes to include in the output and statistical post-processing of the nodal loads. Thus the total number of records for post-pressing is Terminal-Initial+1.
