If you're talking about opening and running a script in 1 file with a script in a 2nd file, this is definitely possible. In the 2nd file, add the 1st file as an external data source. Then a script in the 2nd file can call a script in the 1st using the Perform Script script step.
If you don't want your files to have external data source references to each other, or if you want to initiate the script from outside of FileMaker Go, you can accomplish that with the FileMaker URL scheme. Look at the URL scheme described on page 21 of the FileMaker Go 13 development guide.
Tank you for your answer.
Let me tell you what I need to do instead of asking for function who could be replaced by better solution that you know.
In FileMaker Go I have the file Call.fmp12 where I have the table In and the table Out.
On the FileMaker Server I have the file StoreCall.fmp12 where there are same table In and Out.
So I need to add all record from table In in the file Call who is on iPad to the table In in the file StoreCall who is on the server and the script must be start from the File Call
and I need to add all record from the table Out in file StoreCall who is on server to the table Out in file Call who is on iPad and the script must be start from the file Call again on the iPad.
I need to do that because the network is not always available.
