I have to read in over 13,000,000 observations [eventually over
33,000,000] with the structure
dataShort = {dataShort, returnNum:0L, x:0D,y:0D,z:0D}
At first, either when reading in or processing, I ran out of memory with
a message about IDL not being able to allocate memory to make the
array. So I read this into an Assoc variable which works fine. Now ,
however, when I try to access parts of this data [dataS is the
Associated structure array]:
datSvX = (dataS.y-yll)/cellsize
I get the error:
% File expression not allowed in this context: DATAS.
Any suggestions would be appreciated. It appears to me that Eric
Korpela's VARRAY refered to in a thread earlier this week will not work
on Win2000 Intel machines. I run Win2000 on a PC with 1Gb RAM and lots
of hard disk space.
