reading from data file in a loop

[Sirat_S_]

Hello Forum

please tell me how to read from a data file in a loop . loop implies its a time data i.e. a block of data, to be read at several time steps. the important concern is how shall the cursor remain at the start of new block of data each time the data file is accessed.

please guide.

Sequential file read position should be retained as long as the file is kept open without rewind.
