expression syntax in TestStand 4.0 tutorial

[Kirika]

Hello All

Teststand is new to me, and I am trying its tutorial with "Using TestStand" manual.

At the Using TestSTand page 3-7, Insert a Template Step step 7, we insert a

message popup "Retry if Previous Step Fails".  This step has post action "Goto Step",

but it doesn't goto next step and uses an expression "RunState.PreviousStep.TS.Id".

I can't find the expression at the expression browser and don't know what this means.

There is a RunState.PreviousStep at the expression browser but no "TS.Id". 

I've attached a pic (teststand_ques.jpg) to show the expression.  Could anyone

tell me its meaning. 

Also, is there any manual or guide of TestStand expression syntax?  I know expression

browser shows its operator and functions, but I'd like to have a detail reference manual.

Thank you

Hi,

The TS is a hidden property of the Step.

You can unhid this property by a setting in the Station Options select the Preference Tab.

You actually dont need to enable this setting, you could of just typed it in (, the .TS.id I mean). But when learning it is handy to see all the properties.

Hi Ray

Thank you! It's the answer I want.

You're also the one who replies my last post.

However, I'd still wonder if we have a guide for

expression.  If so, it would be very helpful for

users like me

Regards,

Hi Kirika,

Have you tried the TestStand Help, the only other place is the help you see in the Expression browser for each function.
