Using calc script function when setting substitution variable value

Question

I would like to be able to execute the below, but this wont work since it is a combination of MaxL and calc script syntax:
alter database 'App'.'DB' set variable 'Var1' @PARENT("Day 1");
The following does not work either for the same reason:
set A = @PARENT("Day 1");
echo $A;
alter database 'App'.'DB' set variable 'Var1' $A;
Is there a correct way to do the above, and is it even possible? Or will the variable literally have to contain the value "@PARENT("Day 1")" to be later parsed in a calc script?

Answer 1

Hi James. I was hoping that 'query database' with the 'member info' option was going to include the parent in the result set, but it's just a bunch of storage / consolidation properties so no luck there.
The only idea i could come up with (and this is getting pretty clunky) would be to use MaxL to execute a report script (or MDX query, but the output would be different and probably harder to parse):
//ESS_LOCALE English_UnitedStates.Latin1@Binary
{SUPHEADING}
{TABDELIMIT}
<ROW("YourDimension")
<PARENT &YourSubVar
!This spits out a tab delimited file containing just one line - the name of the parent of the member named in &YourSubVar, and one data value, tab delimited. You could then parse the output in cmd (I'm assuming you're on Windows) using FOR /F to grab the first value and then pass it back in to a subsequent MaxL command to update the value of the second subvar (as referenced in your fix).
