Although this is a pre-FileMaker 7 example, I continue to have people request it. I was able to dig it up from the archives and post it here. It does show some interesting techniques but could use some updates such as employing script variables.

Here I show how you can copy a portal row and paste it into a new portal row. We do this by using a script and a few FileMaker text functions to concatenate and parse a global field.

Here are the basic steps we took ...

- Created the two files and defined a relationship between them using the state field

- Made sure the relationship allowed us to create new related records

- Added the portal to the layout of the parent file and made sure it had a vertical scroll bar

- Created a global field to hold all the contents of the portal row

- Set the global field equal to the contents of the portal row

SET Copy Portal Row Global - child::Company & " | " & child::Contact & " | " & child::Phone

so here we used a calculation to concatenate each of the fields in the portal into one field. We separated the data in each field by putting a text string " | " between them. This gives us a marker of where the data in a field starts and ends. You can see how this works when you click the Copy Row button in a portal row.

- Next we added a button to the first portal row. This button will appear in all the available portal rows to perform the script we just created. I used a merge field from the child file so that the button would only appear in rows that have information.

- I added a delete portal row button to the first portal row but it is not essential to the technique

- Next we created the script to create a new portal row and paste in the information we previously copied. It breaks down into the following steps

GO TO PORTAL ROW - last
** This is how we are creating a new record**

SET FIELD - child:Company
Left(Copy Portal Row Global,
Position(Copy Portal Row Global, " | ", 1, 1))
** This pulls all the text characters left of the first " | " marker**

SET FIELD - child:Contact
Trim(
Middle(Copy Portal Row Global,
Position(Copy Portal Row Global, " | ", 1, 1) +2,
Position(Copy Portal Row Global, " | ", 1, 2) - Position(Copy Portal Row Global, " | ", 1, 1)-2))
** This pulls all the text characters between the first " | " marker and the second "|" marker. It also trims any leading or trailing character spaces.**

SET FIELD - child:PHone
Trim(Right(Copy Portal Row Global,
Length(Copy Portal Row Global) - Position(Copy Portal Row Global, " | ", 1, 2)-2))
** This pulls all the text characters right of the second " | " marker. It also trims any leading or trailing character spaces.**

- Finally, I added a button to the layout the runs the paste script we just created.
