I have created a SAVE file (my_app.sav) containing several PRO files compiles that compose my application. My call the procedure "my_app" to run this application inside IDL. When I run the SAVE file from IDL, entering the following at the command prompt: ------------------------------------------------ RESTORE, 'C:\dir\my_app.sav' my_app ------------------------------------------------ It works very well like this. Since I use several function from ENVI, in the begining of my program I restore the core files and start ENVI in batch mode: -------------------------------------------------------- ENVI, /restore_base_save_files ENVI_BATCH_INIT, log_file = 'batch.log' -------------------------------------------------------- It doesn't block here if I run my program inside IDL. But if I try to use the IDL Virtual Machine... it just refuses to run my code. I tried to open the SAVE file using the IDL VM from several ways... 1) Selecting Start Programs -> IDL 6.4 -> IDL Virtual Machine. I clicked on the splash screen and opened my_app.sav, but then it just opened ENVI and didn't runned my code. 2) Using the Windows command line and I got the same result than before. I think it just restores ENVI files and stops. Why isn't he executing my code? Any suggestions? Thank you in advance, Paulo Resende
