Dear all, I am post-processing the trace file. here is part of my data file after process, and this file is called ff.tmp. I want to read data from tt.tmp and put data into a 2-Dimension array. Does anybody help me give me a sample? Thank you very much. Grace 93 2 11 3 95 1 10 5 11 4 94 2 10 6 96 1 12 3 95 2 11 5 12 4 97 1 11 6 96 2 13 3 98 1 12 5 13 4 12 6 14 3 13 5 13 6 15 3 14 5 14 6
