where offsets are bit based
Example:
SendSSPFrameCommand_Initiator
{Data = LRF[startBitOffset:endBitOffset] )
Tag = 0x101}
The constraints are 1) Length bigger than 64 bit is not supported and 2) Offsets
(StartBitOffset and EndBitOffset) should be in same DWORD, except for length bigger
than 32.
 Random values: @varName1 = Random
5.13.3 Expression on Variables
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
5.13.4 If/While in Logical Expressions
Like programming languages, scripts allow conditional statements. 
The if/while syntaxes are:
If (expression)then
{
….
}
else
{
….
}
While(@VarName)
{
…….
}
Example for if, then else:
