In order to reduce the memory footprint of the IDL workbench, find the
following file based on the location of your 8.0 installation
directory:

C:\Program Files\ITT\IDL\IDL80\bin\bin.x86\idlde.ini

Open that file in a text editor and it should look something like
this:

-vm
C:\Program Files\ITT\IDL\IDL80\bin\bin.x86\jre\bin
-vmargs
-Xms256M
-Xmx768M
-XX:MaxPermSize=128m

The important lines are:

-Xms256M
-Xmx768M

The -Xms parameter tells the workbench how many megs of RAM to
allocate at startup and the -Xmx parameter tells the workbench how
many megs of RAM it can grow to (should be equal to or larger than the
-Xms setting). You can reduce these numbers to solve your problem.

I would not recommend reducing them lower than:

-Xms128M
-Xmx128M

however since the workbench needs at least 128 megs to run properly
without hiccups.

Cheers,
Scott
