Not directly, but see below. > <hansl> > open andy.gdt > print 1 > # the help for "series" says " In the context of a genr formula, existing > variables must be referenced by name, not ID number." > # but using the id of a series is possible with other commands > series test= sales - price > > # so isn't it possible to have something like > # series test2 = id[1]-id[2] [...] > <hansl> There's a varname() function but that won't do what you want: series test2 = varname(1) - varname(2) will fail since the value yielded by "varname(1)" is a string, not a series. The way to do it is by using a list: <hansl> open data4-1.gdt series test = price - sqft list ID = dataset series test2 = ID[1] - ID[2] print test test2 -o </hansl> Allin Cottrell ------------------------------ _______________________________________________ Gretl-users mailing list Gretl-users(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-users End of Gretl-users Digest, Vol 108, Issue 20 ********************************************
