You can map same file from two different J sessions to read and write. I have experienced this and it works. For example you can have a result file mappe and one process to write the first half of the result file and and other process to write the second half. Anssi

I can imagine it being ok to at least write to it from one session and reading it at the same time from other sessions. How well it works to write to the same file from several J sessions at the same time would be interesting to know, -- Björn Helgason, Verkfræðingur Fornustekkum II 781 Hornafirði Po Box 127,801 Selfoss , t-póst: [email protected] gsm: +3546985532 sími: +3544781286 http://groups.google.com/group/J-Programming Tæknikunnátta höndlar hið flókna, sköpunargáfa er meistari einfaldleikans góður kennari getur stigið á tær án þess að glansinn fari af skónum /|_ .-----------------------------------. ,' .\ / | Með léttri lund verður | ,--' _,' | Dagurinn í dag | / / | Enn betri en gærdagurinn | ( -. | `-----------------------------------' | ) | (\_ _/) (`-.
