## Dynamic calculation in table possible?

Dear All,

Could you please tell me whether a dynamic calculation is possible?

Imagine I have a table like this (in script editor):

Table1:

Load * INLINE [

Var1, Var2, Var3,Var4,Var5

1,5,6,5,7

2,6,8,1,9

10,5,8,2,9

];

Table2:

LOAD (Var1 + Var2 +Var3) as [sum all var]

Resident Table1;

This simple situation becomes complex when

• Table1 has 500 columns from Var1 up to Var500
• Table1 has different column names, so Var1 = Thickness, Var2 = Spreadability
• The sum of Var1..,.Var500 varies depending on the data structure and user selection
and as a consequence not all columns will be concerned in computation e.g. (Var1
+ Var2) as [sum all var],  (Var12 + Var13 + Var273 + Var303) as [sum all var] etc. a LOT of possibilities.

As you may see, this is an example of dynamic environment. I suppose that this can be solved with a
macro program but I’m not very sure.

Can you please demonstrate it how to solve this?

Thanks and best regards,

Cornelis

```Table1:
Load rowno() as row, * INLINE [
Var1, Var2, Var3,Var4,Var5
1,5,6,5,7
2,6,8,1,9
10,5,8,2,9
];

Temp:
CrossTable(Var,Value)
load  * Resident Table1;

join(Table1)
load row, sum(Value) as [sum all var]
Resident Temp
group by row;

drop table Temp;
drop field row;
```

Instead of variables, it would be perhaps better to handle these as values of dimension.

var1, ..., var500 could become values of a dimension that you will sum up by selecting them.

Thanks for your answer.

Do you have an example to demonstrate this, using the example above?

Yes, that is the answer where I'm looking for!

The crosstable option is the best to handle columns in a dynamic environment.

Best regards,
