===== Memory =====


  * JAS runs best on machines that have at least 2 gigabytes of memory. 
  * JAS is written in [[http://www.instantiations.com/VAST/index.html |Visual Age Smalltalk (VAST)]]. VAST is a 32 bit application that is compiled with the [[http://www.microsoft.com/whdc/system/platform/server/PAE/PAEmem.mspx|/LARGEADDRESSAWARE]] switch, which means that JAS can use "1 GB of additional virtual address space above 2 GB".
