TEXT Literals

A literal of type text may need to have carriage returns inserted within them to make screen text readable.

For example, to have the string

Test1Test2Test3 show up on separate lines, insert the '$' character

wherever a new line is desired. Internally, the scripting engine inserts the carriage returns as in

Test1$Test2$Test3.

Arithmetic

The scripting engine supports simple algebraic expressions including parenthesis nesting, unary minus

(negation), and +,-./,*. It does not support nested functions in expressions since scripting functions do not

return a value. This is in keeping with the BASIC language paradigm.

Assignment: MyIntegerVariable := (2 * (MyPixel[J] - BIAS/100)), where := is the

assignment operator.

Evaluation: IF(MyVariable1 = MyVariable2) GOTO RESET, where = is the boolean

comparison operator. Please note that

:= and = are not interchangeable.
