I checked it again. It works in FP7.
To the best of my knowledge this is what I do. It has been done over a 1000 times in the last year with out a hitch on both a PC and a Mac:
One takes a raw data stream from a secure page on our web site, with 39 fields of data per record and copies it to the clip board. A Filemaker script in the main file is then run which does a little housekeeping and then calls another script in another FileMaker file which pastes the clip board to one of its fields. It strips out one record by looking for an end of record marker and puts that record into another of its fields. It then operates on that record in the field and finds all the field data separators and replaces them with tabs. (The "replace" symbol look like a square on my PC). It then exports the resulting field into an external file called data.tab. (When I use fp7, data.tab definitely has tabs in it but not in fp8.5.) Control returns to the main script which imports the data from data.tab as tab separated data into 39 fields in a new record in the main file. This repeats until all the records have been done.
When I do it in fp8.5, all 39 fields pile up in the first field as there are no tabs to separate them out.
Anyway, if I can't make it work in fp8.5, I will need to either stay with FP7 or find another way to make it work.
