Re: 回复： report a bug of the function of patsplit

[Andrew J. Schorr]

Hi,

Please always respond to the list instead of privately.
You answered half of my question, but not the more important half: how
do the results differ from what you expect? As Wolfgang pointed out,
the patsplit function seems to be working correctly, as far as I can tell.
And yes -- you should upgrade to the newest version of gawk.

Regards,
Andy
