SELECTRULE Subcommand (CSSELECT command)

SELECTRULE generates a text file containing a rule that describes characteristics of selected units.

• The selection rule is not generated by default.
• OUTFILE specifies the name of the file. If the file exists, it is overwritten without warning.
• The selection rule is written in generic notation, for example—(a EQ 1) AND (b EQ 2)’. You can transform the selection rule into SQL code or command syntax that can be used to extract a subframe for the next stage of a multistage extraction.
