#### 15.7.10.2 PPROPERTIES ¶

    /PPROPERTIES &postcompute...
        [LABEL=string]
        [FORMAT=[summary format]...]
        [HIDESOURCECATS={NO | YES}

The `PPROPERTIES` subcommand, which must appear before `TABLE`, sets properties for one or more postcomputes defined on prior `PCOMPUTE` subcommands. The subcommand syntax begins with the list of postcomputes, each prefixed with ‘`&`’ as specified on `PCOMPUTE`.

All of the settings on `PPROPERTIES` are optional. Use `LABEL` to set the label shown for the postcomputes in table output. The default label for a postcompute is the expression used to define it.

A postcompute always uses same summary functions as the variable whose categories contain it, but `FORMAT` allows control over the format used to display their values. It takes a list of summary function names and format specifiers.

By default, or with `HIDESOURCECATS=NO`, categories referred to by computed categories are displayed like other categories. Use `HIDESOURCECATS=YES` to hide them.

The previous section provides an example for `PPROPERTIES`.
