TestView Command | General | Assign

Assign Dialog Box

The command Assign is used, as the name implies, to assign values to variables. It is necessary to initialize variables in many cases:

For the if expression in a loop to function
To evaluate expressions before using them in other commands such as Miscellaneous or Pause/message (which does not support expression evaluation)
To output signal values or component parameter values in a tableOut report

If a variable is not initialized before being used in the Processing command or Expression command for instance, it will cause an error and the test sequence will abort.

This command uses the ScopeView calculation engine, meaning that it is possible to use the functions from ScopeView (e.g. ‘max’). For all intent and purposes, ‘Eval’, ‘Expression’ and ‘Assign’ yield the same result, the only difference is the visual presentation of the dialog box and the capability to process one or more expressions.

Differences:

Eval	Can only evaluate one expression.
Expression	Can evaluate several expressions.
Assign	Can evaluate several expressions and has the ‘multi-param’ mode.
