v7 Upgrade issue - @ sign in filename....

I've got .ftm files that start with "@" (at sign) that could be filedef'd and read fine in 5.3.4, but now cause "Unknown Error Occurred" errors in 7.1.4. Is this a known issue and is there a known workaround I can use that doesn't involve renaming all my files?

As per 5.2 (and later!) documentation -

quote:
The following rules apply:

The file name can be up to 64 characters long. The first character should be a letter, and the remaining characters can be any combination of letters, numbers, and underscores. Other special characters may be used, but could cause problems and are therefore not recommended or supported.

Looks like you are the victim of code tightening.

In fact, checking back through old release documents in the technical documentation link above, even 4.3 mentions that -

quote:
The file name must start with a letter, and the remaining characters can be any combination of letters, numbers, and underscores (_).

At this version I haven't (yet?) located any reference to the fact that special characters can cause problems.

Although these references are for data sources, you could virtually guarantee that if a language has restrictions on file names for data sources it implies that the same would go for any file that it can reference.

As Mickey implied in months past (I think it was Mickey anyway) if you use something because it just happens to work then don't expect it to always work.

Not a lot of comfort, I know, but all the releases I have ever used have come with a new raft of code tightening.

Hi InsideTGT,

Has this issue been resolved on your site?

I ran some search on documents and then realized that the error message is relatively generic that does not give much details on what the actual cause is. Tony's suggestion is a good one to start looking at (many thanks Tony

). If you need additional information and/or would like to check more details, I would strongly suggest you to contact Information Builders' Customer Support Services for assistance. The phone number is 1-800-736-6130, or you can access InfoResponse at any time.

Hope this helps.
