Mirek,
Thanks for your speedy response (and the others who've replied too)...

I have installed octave-2.1.42-windows-atlas.exe binary from
octave.sf.net on a Windows2000 PC, selecting the octave-2.1.42-p4atlas
version. Although I have ~ 1 Gb memory, Octave seems to give a "memory
exhausted" error message when it hits the 256 Mb boundary,
that points to

I've modified the registry as suggested, by running the following within
the rxvt.exe terminal:
/bin/regtool.exe -i set /HKLM/Software/Cygnus\
Solutions/Cygwin/heap_chunk_in_mb 1024
Restarting the PC and running Octave, the changed registry entry is visible:
>> system('/bin/regtool.exe -v list "/HKLM/Software/Cygnus
Solutions/Cygwin"')
mounts v2 C__quartus_bin_cygwin_bin_cygwin1_dll\ (cygnus)
Program Options\ (cygnus)
heap_chunk_in_mb = 0x00000400 (1024)
ans = 0
Unfortunately, it does not seem to have been picked up:
>> clear all;a = zeros(5000,6500)
error: memory exhausted -- trying to return to prompt
Any ideas? Perhaps I need a later version of Octave for this feature?
