"No Records Found" in Script

[mikemccloskey]

Is there a way to tell a script - When you perform a find and the results are "no records found" to continue automatically or to otherwise continue to the next step?

Use the Status(CurrentError) function, if it's equal to 401, do whatever.

You can also use Status ( CurrentFoundCount ) = 0

Don't forget to SetErrorCapture (on) before you use tests in a script. Otherwise the dialog will still be displayed. -bd

The "Set Error Capture=on" script step stops FMP from displaying the messages and is definately needed here. Just remember that this step disables FMP's internal error checking and *you* the developer are now responsible for trapping errors. For instance, if you peform a find then follow it with a delete all, what will FMP do with an empty found set?

Use the Status[CurrentError] function in combination with If[] steps to provide solutions to these error situations.

Note that the Status[CurrentError] function returns the value for the script step that just immediately ran. So if you perform a find, then change layout, then check the currenterror status, the error status will be for the change layout step not the find (so it will probably be zero).

To work around this problem developers often create a global field and store the error status in the field. The example would now look like this

perform find

set field global=Status[CurrentError]

change layout

If[global=401]
