I don't experience your limitation ...

iMi7:jstuff jkt$ j6
   JVERSION
Installer: j602a_mac_intel.dmg
Engine: j602/2008-03-03/16:45
Library: 6.02.023

   NB. I have a couple of files that are text digits of pi ...
   NB. host is a nice wrapper for 2!:0

   host
[: 2!:0 '(' , ' || true)' ,~ ]

   $pi=. host 'cat Pi33554433.txt'
33554434
3.14159265358979323846264338327950288419716939937510

  NB. No trouble, even for much larger results

$Lpi=: 2!:0 'cat "~/Downloads/pi/y-cruncher v0.5.5.9187 (fix 2)/Pi - Dec - Chudnovsky.txt"'
500000002

Perhaps it is some setting in your Darwin environment?

AFAICT the returned value from 2!:0 in j602 running on Darwin is limited to

Is there an easy way to increase this value, eg to double it?
