NUMERIC explicitly declares new numeric variables, optionally
setting their output formats.
NUMERIC var_list [(fmt_spec)] [/var_list [(fmt_spec)]]...
Specify the names of the new numeric variables as var_list. If you wish to set the variables’ output formats, follow their names by an output format specification in parentheses (see Input and Output Formats); otherwise, the default is F8.2.
Variables created with NUMERIC are initialized to the
system-missing value.
