Subject: [Jprogramming] awk-like J sentences?
Hey there,
As new user to J (but several years experience with C and Java), I
find it very, very interesting. The power of its one liners and
mathematical heritage really have me hooked. I was wondering though
if it has similar capabilities as awk. What's the equivalent to this
awk script in J?:
BEGIN { FS=";" }
{ print $1+$2 }
This script sets a FieldSeparator to ;, and then for every "row", add
the first and second column and prints it. I would like to replace awk
with J!
Thank you,
Lee
P.S. Excuse me if I've misidentified J sentences. (Sentences -> statements?)
