Hi
I have a problem with reading data in fortran 90. my programs try to read a txt file that only contains one number in it but if the txt file is empty it stops. i want to make it continue what should i do?

Look up the ERROR= option for the READ statement.

Even better, look up the END= option.

ERROR= might pick up any type of error, not just that the file doesn't contain enough data.
