Hi Devon,
I just launched J6.02 and loaded 'tables/dsv'. Chopstring is there.
load 'tables/dsv'
chopstring
3 : 0
(' ';'""') chopstring y
:
dat=. y
'fd sd'=. 2{. boxopen x
assert. 1 = #fd
if. =/sd do. sd=. (-<:#sd)}.sd NB. empty, one or two same
else. NB. replace diff start and end delims with single
s=. {.('|'=fd){ '|`' NB. choose single sd
dat=. dat rplc ({.sd);s;({:sd);s
sd=. s
end.
dat=. dat,fd
b=. dat e. fd
c=. dat e. sd
d=. ~:/\ c NB. mask inside sds
fmsk=. b > d NB. end of fields
smsk=. (> (0 , }:)) c NB. first in group of sds
smsk=. -. smsk +. c *. 1|.fmsk NB. or previous to fd
y=. smsk#y,fd NB. compress out string delims
fmsk=. 0:^:(,@1: -: ]) smsk#fmsk
fmsk <;._2 y NB. box
)
Maybe something screwy with your addons?

Subject: [Jprogramming] "chopstring" in J6?
Hi All -
last night at NYCJUG, Ken told me about a J-supplied script that
provides
the functionality I'd rolled myself of reading tab-delimited files into
handy 2-D arrays: ~addons/tables/dsv/dsv.ijs.
When attempting to use this in J6, I got a value error because
"chopstring"
is not defined. In J7, it worked fine as "chopstring" is defined in
"stdlib.ijs". I couldn't find this function anywhere in J6, so I'm
wondering why it gets used in dsv. It's possible I've mis-loaded addon
directories between J6 and J7, so does anyone use this in J6?
I notice that the "stdlib" looks very different between the two versions
of
J.
Regards,
Devon
