Hi,All
I have to convert some data which is saved in IDL format
by other group using the full version of IDL to text format
or normal binary format. We have not IDL on our local machine.
Is there any other software that can do this conversion? Can student
version of IDL do this job? Thanks.
Regards
Helin Wei

Helin,
Here are some options:
(1) Convince the other group to write binary or text format data.
(2) Purchase a licensed copy of IDL (with educational discount, the cost
is < $1000).
(3) Follow the steps below to read the data:
Download and install the free demo version of IDL for any Unix platform
from
ftp://ftp.rsinc.com/pub/idl_5.2
Say the saved data was a single array named ARRAY, and it was saved in
IDL using this command:
IDL> save, array, file='data.sav'
then to restore the data in IDL, the command is
IDL> restore, file='data.sav'
To get text format output, create the following script and name it
test.pro:
restore, file='data.sav'
print, size(array)
print, array, format='(10e13.6)'
exit
Then execute the script using the following Unix command:
% idl test.pro > test.out
This will cause the contents of ARRAY to be saved as text in test.out.
The SIZE command prints the number of dimensions, the dimension values,
the data type code, and the number of elements.
Cheers,
Liam.
