Considering that I have two parameters:
Parameter1(a,b,c,“age”)
Parameter2(a,b,c,“SiteIndex”)

How can I create:
Parameter3(a,b,c,“age.SiteIndex”)?

I mean, what I’m wondering is if there is a way of putting together both parameters creating a “unique” index, which I will use to extract value from a lookup table.
Ps.: I don’t want to sum up both parameters, I simply want to “glue” them.

age(a,b,c) 'Your original parameter1',
siteIndex(a,b,c) 'Your original parameter2'
allstuff(a,b,c,*)
allstuff(a,b,c,"Age') = age(a,b,c);
allstuff(a,b,c,"siteIndex") = siteIndex(a,b,c);

or like this:

set d /"Age", "Index"):
parameters
age(a,b,c) 'Your original parameter1',
siteIndex(a,b,c) 'Your original parameter2'
allstuff(a,b,c,d)
allstuff(a,b,c,"Age') = age(a,b,c);
allstuff(a,b,c,"siteIndex") = siteIndex(a,b,c);
