EXPORT /OUTFILE='filename' /DROP=var_list /KEEP=var_list /RENAME=(src_names=target_names)...
The EXPORT procedure writes the active file dictionary and data to a specified portable file.
The OUTFILE subcommand, which is the only required subcommand, specifies the portable file to be written as a file name string or a file handle (see FILE HANDLE).
DROP, KEEP, and RENAME follow the same format as the SAVE procedure (see SAVE).
EXPORT is a procedure. It causes the active file to be read.
