insufficient memory problems

[Jon Belak <jbelak@xxxxxxx>]

Hello,

 

I'm having memory problems when I try to use Ferret 5.50 (win32) on a computer running Windows 2000.  When writing and listing the file c:\tmp\right_anom.cdf (see code below), I get the message "**ERROR:  insufficient memory:  12614400 words were requested."  I tried to increase the memory using SET MEMORY/SIZE, but the error still appears.  I also attempted to follow the instructions in the installation and update guide for increasing environment space, but the memory tab described in the guide does not exist in the properties gui that appears when I right click on the ferret icon.  Does anybody know why I might be getting this message, and how to rectify memory allocation problems in Windows 2000 version 5.0?  The computer I'm using has 392 mb of RAM.

 

Another problem I'm having relates to the coads_climatology data.  When I use these data in various tutorials and jnl files, I frequently get the message "aborted due to illegal limits" in reference to the time domain.  I know the commands I'm using should work because they are in the tutorials that come with the software.   

 

Any help would be greatly appreciated.  I'm pasting the code below.
