1 Replies and 2110 Views Old program not working on new system  2110  1 Started by  Deleted User An IDL user has asked the following question: I upgraded to 8.5 earlier this year (License ID: 5500131) as I am now running OS X Yosemite (10.10) and a data processing program I used previously not longer works. This is an old program (circa early 2000s) that reads binary data files from an older satellite and produces a save set of the data. When I use the program in the present idl version, the data it produces is garbage. It appears to be a problem with reading the binary file.

Unfortunately IDL's need to define everything prior to use has made it rather more difficult than other programs to do this. The code below is roughly what I would like to do. (Although obviously it doesn't work like this) for i=2,55 do begin S...
