Reading files with unknown amount of data [message #1467]

I am trying to read a data file containing an unknown amount of data into
arrays in IDL. I know the format of the data in the file, but not the number
of pieces of data in the file. Currently, I read the file twice; once to
determine the amount of data in the file and then a second time to actually
read the data into an array (now that I know the size of array needed).
Is there a better way to do this (without having to read the file twice)?
