Perhaps it appears to not need it. But what would you say it requires more computation:
A simple logical operation or a call to split and then loop on it
{n=split($2, a, ","); for (i=1; i<=n; i++)
It is a choice to skip the second more expensive computation for lines that do not need it.

What I want to do is just delete some lines from a text file, I know it's easy using copy and redirect function, but what I have to do is edit this file (delete the lines) directly, as new lines may be added to the text file during this period. Can AIX do this ?
