Dear Al,

It's unclear question.

For start, what version of IDL or ENVI+IDL do you have ?

If you havent any and your IDL source code in file with SAV extension, then you must find IDL virtual machine (IDL VM). But even in this case there is no guarantee that your code will work because of a some of restrictions

with regards

Vladimir

Hello,

As what Vladimir said, the question is a little unclear.

Anyway, try searching on YouTube for specific videos. Most likely you'll find one that suits your need. For instance, this account has videos posted about IDL: https://www.youtube.com/channel/UCIsi_Gwax_57fTDwdDWgufA

Cheers!
