... could be a lot of things described in -help syntax-, and since we
did not know what kind of program you were writing we just left that
open by typing ... It could be nothing at all, but often it is
something like this:
syntax varlist [if] [in] [fw aw pw] , ///
values(numlist min=6 max=6 >0 <50 sort integer)
In which case someone must enter a list variables and your list of 6
integers, and one can use -if- -in- and weights (fweights, aweights, or
pweights). If you want to allow for -if- and -in-, it is useful to take
a look at -help mark-.
If All you want is to pass the six integers, you can type:
syntax , values(numlist min=6 max=6 >0 <50 sort integer)
The example below illustrates some of the useful features of -syntax-
in a working example.
Hope this helps,
Maarten
