SHOWVAR SUBSCRPTED VARIABLES

[Chaboud Christian]

Good evening,

I'm using Vensim DSS 8.1.1 for windows.

I have made a Venapp using the SHOWVAR command to show variables values.

For subscripted variables it works well when asking to show values for specified values of the subscript.
But It doesn't work when using the subscript name in the SHOWVAR command.

for instance if the subscrpt s has to values S1,S1, and the subscripted variable is A

SHOWVAR A[s1] or showvar[s2] are OK but SHOWVAR A[s] gives no result.

Thanks four your Help

SHOWVAR A[s1] or showvar[s2] are OK but SHOWVAR A[s] gives no result.

The help says that it should work and display the first subscript element selected. Do you have any subscripts selected?

[Chaboud Christian]

I did select subscripts ...I did succesfully use that command with an older vensim version....

If no element is selected, it should show the first element, so this sounds like a bug. But we can't easily judge without a test case. Can you share the code for the screen?

[Chaboud Christian]

Ok, I send you the following elements showing clearly yhe problem :
a small vensim program (test.mdl) and a Venapp using it (test.vcd)
SHOWVAR is used in the OUTPOUT1 view of test.vcd
Showvar[a1] and Showvar[a1] : ok !
Whowvar [a] : error !
