   • In Mac OS 7.5 and later, in the information window you will see anarea labeled 'Memory Requirements'. In the 'Preferred size:' field,enter the amount of memory you'd like to allocate to the application.You cannot change the 'Suggested size:' field. The 'Minimum size:'field indicates the amount of free RAM needed to permit theapplication to run. If the 'Preferred size:' amount is unavailable, aslong as your computer has enough RAM to satisfy the minimumrequirement to run, the application will be available.
   • In Mac OS 7.1 and earlier, near the bottom of the informationwindow you will see an area labeled 'Memory'. In the 'Current size:'field, enter the amount of memory you'd like to allocate to theapplication. You cannot change the 'Suggested size:' field. Bear inmind that you will always need enough free RAM to cover the newamount, or the application will not run.
