RE: Modify a topspeed table gives an error Hoon (Programmer) 7 Oct 03 18:23 Error 13 or Internal error 513? I am searching for an answer to this as well. I want to add a field to an existing table - can't do it even if the table is in a new app and has no records yet. Can't find any reference to those errors. RE: Modify a topspeed table gives an error ShankarJ (Programmer) 8 Oct 03 01:40 There were some references to Error 13 and Internal Error 513 in the Bug Reporting/FAQs of the SoftVelocity site. From what I remember, the bug was there in previous versions of C5.5 and specific to certain OS. Please make sure that you upgrade to the latest version.
