SETVARVALUESONLINKUPDATE keyword
This keyword is designed to cause variables in a child linked form to be updated every time the child form is refreshed by the parent form (because properties in the LINKBY spec change). It is similar to the SETVARVALUES keyword, which is designed to pass values into a child form's variables as the child form is launched.
The format of the parameters for this keyword is identical to those for the SETVARVALUES keyword (e.g., the parms for this keyword have the form var1=value1<,var2=value2>, etc.), but the variables are reassigned dynamically every time the linked child form is refreshed due to changes in the parent form.
