Note that with 20 fields on each of 3,000 input records being combined into 200 output lines, your average output lines with have 300 fields and some lines could have many more. You don't give us any indication of what system you're using, nor of the contents of most of the input fields. The awk utility and most editors are only defined to work on text files, and by definition, lines in a text file can't be longer than LINE_MAX bytes (including the terminating newline character). (Try:
to determine the value of LINE_MAX on your system. The standards only require that implementations support lines up to 2,048 bytes per line.) Are you sure that none of your output lines exceed LINE_MAX?
If you ask awk to print a line that is longer than LINE_MAX bytes long, the results are unspecified. If you use ed, ex, grep, sed, vi (or any of LOTS of other standard utilities that are described as processing text files) to read or write or create internal lines longer than LINE_MAX bytes long, the results are unspecified. There are very few standard text processing utilities that are defined to work on lines with arbitrary lengths (cut, fold, and paste).
