Dear All,
  1. While programming a dialog one can use an option numeric for the VARNAME dialog elements, which is not mentioned in the documentation, but is used extensively in Stata's base dialogs. I wonder whether this omission in the documentation is intentional (the option is undocumented in the sense of help undocumented) or unintentional (and will be fixed).
  2. The element VARNAME doesn't allow options onchange() and onselchange() present in other dialog controls. How can I program a reaction to the selection of a variable or a manual edit in this field (equivalent of onchange() for the EDIT elements)?
Code:
VARNAME  vn_s     150  @   100  ., option(vs) numeric default() onchange(program schanged)
option onchange() not allowed
r(198);

VARNAME  vn_s     150  @   100  ., option(vs) numeric default() onselchange(program schanged)
option onselchange() not allowed
r(198);
Thank you, Sergiy Radyakin
