[Jprogramming] CSV Output

[Sherlock, Ric]

My first reaction would be to replace the 'fwrites' verb in the last
line of 'writecsv' with 'fappends'.

Maybe there is the case for adding an extra verb ('appendcsv') to the
csv script?

writecsv=: 4 : 0
dat=. ,each 8!:2 each x
f=. '"'&,@(,&'",')@(#~ >:@(=&'"'))
dat=. f each dat
f=. <@(,&LF)@}:@;
dat=. ;f"1 dat
dat fwrites extcsv y
)

appendcsv=: 4 : 0
dat=. ,each 8!:2 each x
f=. '"'&,@(,&'",')@(#~ >:@(=&'"'))
dat=. f each dat
f=. <@(,&LF)@}:@;
dat=. ;f"1 dat
dat fappends extcsv y
)
