Whats wrong with my expession?

[1984]

Hi,

whats wrong with this expression?

(( Locals.ChannelA.Info.Input.ID.Name != "" ) && ( Locals.ChannelA.Info.Output.ID.Name != "" )) ? ( Locals.ChannelA.Limits = Locals.Limits.LimitsList[ Val( Locals.Test.Current.ChannelA.LimitName ) ] )

The error messages says Unexpected token: "?". Basically I'd just like to implement an IF structure. The expression is in expression tab of a statement type step.

Must be something mega obvious...

Thanks,

ANSI C defines a boolean if clause as <Boolean Criteria>?<TRUE>:<FALSE>.

Looking at your expression, there is the complete <FALSE> branch missing.

EDIT: I stated the part with ANSI C because TS is implementing the same syntax

I see... is there a "do nothing" command in TestStand? Or should I just put simply a False constant to the false branch?

False should work fine, but my favorite is to use the keyword Nothing

Thanks! All clear now.
