Specifications

NOTE Identifiers are case sensitive. The names My_array and my_array reference
different identifiers.
Special Identifiers
for Channels
Channel identifiers appear as variable identifiers within the algorithm and have a
fixed, reserved syntax. The identifiers I100 to I163 specify input channel numbers.
The “I” must be upper case. They may only appear on the right side of an
assignment operator. The identifiers O100 to O163 specify output channel numbers.
The “O” must be upper case. They can appear on either or both sides of the
assignment operator.
NOTE Trying to declare a variable with a channel identifier will generate an error.
Operators The VT1419A’s Algorithm Language supports the following operators:
Assignment Operator = (assignment) example; c = 1.2345
Arithmetic Operators + (addition) examples; c=a+b
- (subtraction) c=a-b
* (multiplication) c = a * b
/ (division) c=a/b
Unary Operators - (unary minus) c=a+(-b)
+ (unary plus) c=a+(+b)
Comparison Operators == (is equal to) examples; a == b
!= (is not equal to) a != b
< (is less than) a < b
> (is greater than) a > b
<= (is less than or equal to) a <= b
>= (is greater than or equal to) a >= b
Logical Operators || (or) examples; (a == b) || (a == c)
&& (and) (a == b) && (a == c)
Unary Logical Operator ! (not) example; !b
