Catch Method similar to VBA

Jouher_20929

In VBA, we have lot of error handling say like:

On Error GoTo ErrorMsg

          --> Code

Done: 

   Exit Function

Error Msg;

  - do in error case

 

 

I sthere any similar way in TCL??

Hello,

 

Most commands supporting the catch error handling.

 

if { [ catch {command_name...} ] } {

     # Handle error

}

 

e.g. error handling if already a panel is open, it is not allowed in HW to stack panels:

 

            if { [catch {*createmarkpanel lines 1 'Select first line ...'}] } {
                set Info01Label 'Warning: Can't Stack Panels'
                update
                return
            }
 

Best Regards,
