TestView Command | General | Expression

The Expression command is used to calculate some mathematical expressions and save the result into a variable (which is necessary as some other commands can't evaluate expressions). It can also be used to initialize variables (which is necessary for other commands to work).

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.
