Hi all, I am new to Perl and am trying to do the following. I have a dataset file with the following example structure.
ACRU 12 34 QUAL 28 90 QURU 3345 . . . . . QUVE 29 88 As you can see, line 3 only contains on 2 columns. "3345" is missing a tab. I have written code to loop through the file and locate those spots. What I would like to do is edit the rows in the data file that have < 3 columns by using substr(). However, when I read each line in as an array, the numeric values are stored as numbers and I am unable to parse them. For example $temp = substr(dat[0],0,2) works for the first element in the array, but $temp = substr(dat[1],0,2) does not work for the numeric values. I receive the error message, "Use of uninitialized value $dat[2] in string". Is there a way around this? thanks for any help.
