You can use this command to work with the variable assignment. You can assign the value to a variable. The right hand side of the equal to operator can be a regular operation for e.g. you can specify something like $var1$ = ( $var2$ + $var5$ - 10 ) / 5.

What are operands supported?

This command supports (, ), /, *, + and - operands. The left and right parentheses take the precedence and the operation within them is evaluated first from left to right.

In the subsequent example ($Var1$ + 5) * ($Var2$ -10), ($Var1$ + 5) will be evaluated first, then ($Var2$ -10) and the result of both will be multiplied together and assigned to the variable specified on the left hand side of the equal to sign.
