Hello ART,

Here are a few tips that may be helpful.....

1) The COMPILE command (IDL Command Line or Console only): http://www.harrisgeospati...m/docs/_COMPILE.html
You can feed the COMPILE command single .pro file or an array of .pro files

2) IDL Projects (Workbench Only): http://www.harrisgeospati...m/docs/Projects.html

Place all the code you want to compile at once into an IDL Project. Then using the Project > Build All process, you can compile all the .pro files within your Project directory at once.

3) The RESOLVE_ALL procedure: http://www.harrisgeospati...ocs/resolve_all.html

This may be helpful, depending on your application.

My understanding of your question is that you are trying to compile a bunch of ".pro" files located in a specific folder. If you are using the IDL workbench and you have you have all of the ".pro" files within the same directory, an easy way to do this might be to do "build project". To do this, you can use the procedure below:

1) Create a new project that includes the folder with the .pro files (if not already created)
2) Right click on the project and then go to "Properties"
3) Click on IDL Build Properties and then uncheck the "Create a save file" option (unless you want a save file to be generated).
4) Click "Apply" and "OK".
5) Right click on the project again and select "Build Project"

All of the .pro files in this directory will then be compiled.
