Getting Value of variable when given name of variable

[BradyJames]

Hello all,

I have some fairly complex logic with ternary operators and I have ran into a snag.  I am using Step.TS.SData.ViCall.Parms.ArgVal to return the input values for my VIs.  However, when I use a variable as an input for my VI, Step.TS.SData.ViCall.Parms.ArgVal will return the variable's name.
An example would be:
Step.TS.SData.ViCall.Parms["RemoteIP"].ArgVal returns Locals.IP

Rather than
Step.TS.SData.ViCall.Parms["RemoteIP"].ArgVal Returns 192.168.0.1

Is there a way to return the value of a variable rather than its name, or evaluate its value given the name?

Thanks,

Brady James

Hi James,

You should take a llok to the TS function 'Evaluate'.

You can easily use it within an expression to get the value contained in a variable only know by its name (as a string).

To find it, click on f(x) within an expression edit box and take a look to the 'Operatros/Functions' tab, section 'Functions', line Other.

Thank you very much! This worked great!
