I would use a custom function called DecToAlpha by Comment (Michael Horak) which can be found here:
You could implement it via script similar to:
Exit Loop If [ Get ( TotalRecordCount ) = 676 ] // this will give you AAA - AZZ (increase this number to keep it incrementing
Set Field [ yourText ; DecToAlpha ( 701 + Get ( TotalRecordCount ) ) ]
The 701 indicates to start at AAA. Actually 702 is AAA but in this script, since you are incrementing via the total record count, you would start your script at 701.
BTW, you may wish to use this in auto-enter or calculation or ... Since I do not know the true purpose it is difficult to do more than provide an example of how it can run. It will be up to you to translate to your needs but let us know if you need help with that translation.
Thank you for taking your time to answer me. I will try your advise. Best regards,
I should mention that you need FM Advanced to create the custom function. But once created in your file (and someone else can put it in for you) then all Users (even those with just FM Pro) can use the custom function.
Thanks for the tip. I use FMP Advance though
