In reply to Leonid Batkhan.

Good question. I assumed that FMTINFO works only on built-in formats, but a quick experiment shows that FMTINFO can get the field width information for user-defined formats.

I posed your question to Rick Langston who is giving a paper on this topic at SAS Global Forum 2017. He says that CATEGORY and DESC are not currently supported but are being considered for a future release. If you attend his talk at SAS Global Forum, let him know that you want that feature.
