Flow Control
Flow control and grouping constructs supported by the expression
language will be a variant of the C language designed to eliminate the
possibility for endless loops and other pathological cases. This variant
includes standard if...then...else statements and compositions.
Example:
//Conditional statement with an if...then clause
if (a_state_0 > 5) { //begin a composition
A_state_0 = 0;
A_state_1 = 5;
} //end composition
else //The else clause is optional and not required
a_state_0 = a_state_0 + 1; //else clause is not
required to be a composition.
Delimiters
Every valid program statement must be terminated using the C-language
style delimiter ‘;’.
For example,
a_in_0 = 0.0;
a_in_1 = 0.0;
Functions
Intrinsic Functions
The Expression block language provides a set of standard functions that
implement some higher math functions, as well as functions for controlling
the status of a value.

Operation Syntax
Conditional if (condition) <statement(s) to be executed for true
case>
[ else <statement(s) to be executed for false case> ]
for loop and while loop constructs are not supported
Composition { <statement> ; ... }
