I am new to FM and am running into a problem while trying to understand some older code. While trying to trace down some scripts stored in other I noticed that I can see the name of the FM file, but not the name of script to run.

Perform [sub-scripts, External: MyFile.fp5 (*)]

I have a script that has a number of these Perform commands in a row.

How do I tell, that script the Perform command will run in the secondary FM file?

Well,

If you have the perform external script chosen, when you select that option, it will show you the file (or let you specify the file) and also the script selected to run.

As a side note, in the perform script command, there is an option for perform subscripts. If this is not checked and in the script you choose there is also a perform script, then this step will be skipped over, because you chose not to perform any subscripts within the selected script.

To add to what Andy said, if you print the scripts, it will also tell you what file and external script is involved.
