I want to use -syntax- with an option, call it x1, which is to be allowed
to be either a real number or a numeric variable. Thus, I want to combine
these two forms into one:
syntax, x1(real)
syntax, x1(varname numeric)
Is there an easy way to do this? I already have a solution, but I wonder
if someone can point out a better way. Here is my solution (the main
syntax also has a newvarname feature):
syntax newvarname (numeric) , x1(passthru)
local newvar "`varlist'"
/* I captured `varlist', because I will now do several other -syntax-
commands (which will wipe out `varlist').
*/
local 0 ", `x1'"
capture syntax , x1(real)
if _rc {
syntax , x1(varname numeric)
}

Thanks to anyone who has a better suggestion .
