Mirek,

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

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?

Richard
