Hi, can anyone tell me how to write a 2D array (1080x540)into an IDL
variable in my hard disk?

Thanks,

Tmorri

Say what!?

How about:

SAVE, array

Or:

OpenW, lun, 'myarray.dat', /Get_Lun
WriteU, lun, array
Free_Lun, lun

Or, if you are going the other way (I can't really
tell):

OpenR, lun, 'whateveritscalled.dat', /Get_Lun
array = BytArr(1080,540)
ReadU, lun, array
Free_Lun, lun

That about covers the usual suspects. Any of those
do it for you?

Cheers,

David
