I am trying to import a spool file (370 characters wide) into the Formtastic Windows Editor GUI, and it truncates the data at position 256. Is there a limitation on character width?
Yes. The spool file width cannot be greater than 256 characters.
You cannot remove any spool files which are linked to spool files. To can clean up the others on the iSeries side by taking option 6 (manual transfer) from the Ftastic0 main menu. You then have to take option 4 to download spool file. Here you can take an option 4 to delete any spool files which are not linked to a form. Once you have cleaned up the spool files, open the GUI and do a download from iSeries. This gets the GUI in sync with the iSeries.
