Lucky Dude ;-) Try this kind of examples on a Mac where the poor memory
alloction
of IDL combines with the even worser memory management of the MacOS !

Things are most annoying for me with IDL 5.0 and ENVI 2.7 ! There is absolutly
no catch up of memory shortage in this software ! Oh yes , you get in ENVI
a message box saying 'Memory is getting low' watching at the same time
IDL crashing in the background ;-(( This problem should be platform
independend (?)

BTW: Does anybody known about the 'optimised' memory settings for ENVI on the
Mac ? There are a few cache, buffer... settings which are not quite clear
to me ??

Servus, Helge
