If you don't specify the
LIBRARY= option on the PROC FORMAT statement, your formats are
stored in Work.Formats, and they exist ...
only for the current
only for the current DATA
only for the current SAS
Correct answer: c
you do not specify the LIBRARY= option, formats are stored in a
default format catalog named Work.Formats. As the libref Work
implies, any format that is stored in Work.Formats is a temporary
format that exists only for the current SAS session.
