Scott,
operations on the IDL8 array still fragile compared to IDL7.1
IDL> data = LONARR(10000, 10000)
IDL> help, data
DATA LONG = Array[10000, 10000]
IDL> help, data[2:*,*]
% Unable to allocate memory: to make array.
Not enough space
% Execution halted at: $MAIN$

Assuming you are on a 32-bit platform, the issue here is there is too
much RAM allocated to the JVM to run the workbench and not enough for
IDL. To increase the memory available to IDL, navigate to the
idlde.ini file in the bin/bin.<arch> folder (a peer to the idlde
executable). That file should look like this:
-vm
{VM_DIR}
-vmargs
-Xms256M
-Xmx768M
-XX:MaxPermSize=128m
Change it to look like this and restart the workbench:
-vm
{VM_DIR}
-vmargs
-Xms128M
-Xmx128M
where {VM_DIR} is the path to the JVM (should not change). This issue
is fixed in 8.0.1.
Cheers,
Scott
