Final answer:
The FMTLIB option in PROC FORMAT, when used with the LIBRARY= option, reports on all formats in the specified catalog. Option d is the correct answer, and this option is useful for getting metadata about stored formats.
Step-by-step explanation:
The correct answer to the question of which statement is true concerning the FMTLIB option in PROC FORMAT when generating a report for permanent formats is that the FMTLIB option in PROC FORMAT prints information about all formats in the catalog that is specified in the LIBRARY= option. Therefore, option d is the correct one. The FMTLIB option is specifically designed to provide metadata about the formats available in a specified library. When you use the LIBRARY= option with PROC FORMAT and include FMTLIB, SAS will generate a report detailing the formats available in that particular catalog.
To use FMTLIB, you would typically write a SAS code snippet like:
PROC FORMAT library=mylib;
FMTLIB;
RUN;
This code assumes that 'mylib' is the libref for the library where your formats are stored. The output will provide information such as the format name, label, type (character or numeric), and range of values formatted.
