How to change and append matrix items of a globaly defined matrix via program?

I want to create a global result table with fixed columns. From anywhere behind the definition of that table I will insert new result lines or modify existing rows. For modification, the first column is a key column, so that the match-Function could give back the row number:

My problem is, that the ResultTable will not be changed. Also not if I write

ResultTable:=AddResult("key123","Cap1","that's a nice result",4.5)

Yes, I know that inside a program the assignments are local. How to make global?

Thank for help!

You have to pass ResultTable as an argument to AdddResult.

Thank you, Stuart

yes that works in that way:

ResultTable:=AddResult(ResultTable,other arguments)

but is there no possibility to change global variables directly?

No. The first time you use ResultTable on the LHS of an assignment in your program you automatically create a local variable with that very name and all subsequent calculations are done using this local variable. So you can't change a worksheet variable from within a program the way you tried to do.

In Mathcad 15 there may be a way of doing it using scripted component - not sure about that and not available in Prime anyway.
