Dear Jiash,
Sorry for the late reply.
I just tested your suggestion. It works very well!!
Thank you very much for helping.
All the best,
nd.

In order to use this, you simply need to write the command you would like to call in a script file (.txt would be fine) and write a loop to let SPAWN to get it started one by one. Once the loop is done, you will see a bunch of IDL sessions running parallel from the Activity Monitor (in OS X) or in the Task Manager (PC). The only problem is that you CANNOT see the output when you run it. You can only track it by looking at the Activity Monitor or Task Manager to see if your IDL sessions disappear or not.

Just create the command string with the full directory of IDL executable file and the name of your procedure, following the same way when you run it in a terminal.
