reading ASCII Data

description: Hello We have ASCII files (floats) with a different number of lines and different number of data in each line. The data was generated by a mass spectrometer software under Win 3.11. Each measurement line ends with '0D'xb instead of '0D'xb and '0A'xb. Is there a way to find the END OF LINE with an IDL function (like EOF) because each line starts with some "header information" which has to be skipped before the measured data starts. How can you handle a variable number of floats? Cheers Mirko
