Dear List
I have written a dialog box program to operate an ado file with the syntax:
program define sampinter, rclass
version 7.0
syntax, Alpha (numlist>0) Power (numlist>0) Delta (numlist >0) [Tau (numlist
>0)] Pcontrol (numlist >=0 <=1) [ Q1(numlist >=0 <=1)] t1(numlist > 0)
t2(numlist > 0) [a1(numlist >0 )] [u(numlist > 0)]
However, when i operate the dialog box, the box itself works, but on feeding
the information into the sampinter program, it issues the following error:
. sampinter, alpha(`main.ed_alpha') power(`main.ed_power')
delta(`main.ed_delta
> ') pcontrol(`main.ed_pcontrol') t1(`main.ed_t1') t2(`main.ed_t2')
a1(`main.ed
> _a1')
option alpha() required
r(198);
Does anyone know a solution to the problem?
Thank you
Sophie
