I'm working with file more than 400K lines, 60 columns. Column count is going to be multiple of 12: 60, 12, 72 or so.
NF/12 gives me on how many iterations I've to do to check certain value.
For example: 7, 14th if only 24 columns in file.
7th, 14th and 21st if 36 columns in file.
I'd like to store and use NF/12 after calculating in BEGIN. But I can't use it.
incr is 0 so this one-liner prints all the columns.
How do I use it later on once calculated in BEGIN?
In the BEGIN section, no file has been opened and read yet, so NF can't be set. And, if I understand correctly, NF changes with every line read, doesn't it? So incr should not be calculated in the BEGIN section, but for every single line.
NF is going to be constant in a file for all the rows.
A file may have a different number of columns. But they are going to be consistent across all the lines.
I hope I'm making sense.
