How can one delete (or purge) an entire directory?
• To purge a subdirectory and all that it contains, type in the name in single quotes, then PGDIR. • To purge all variables in the current directory, but not the directory itself, type CLVAR. Note that with CLVAR, if the current directory contains a non-empty subdirectory, an error occurs at that point, and no subsequent variables are purged.
