Mathematical expressions, such as sum, subtract, and shift:
@varName1 + @varName2
@varName1 - @ varName2
@varName1 & @varName2
@varName1 | @varName2
@varName1 << 2
Logical expressions, such as compare, equal, not, and, and or:
@varName1 > @varName2
@varName1 < @ varName2
@varName1 == @varName2
@varName1 != @ varName2
(logical expression1) && (logical expression2)
(logical expression1) || (logical expression2)
Complex expressions (combination of different operators) with prioritizing supported:
(@varName1 + @varName2) > @varName3
If/While in Logical Expressions
Like programming languages, scripts allow conditional statements. 
The if/while syntaxes are:
If (expression)
{
….
}
else
{
….
}
While(@VarName)
{
…….
}
Note:
In this release, while condition is limited to simple variable values only. Combining operators is
not allowed in while expressions. You should move such expressions inside while block.
Note: Nested while and if are supported.
