Notes

Expressions are strings that contain C-like math to be applied to channels in a database. For example, following an expression: :: "@a = mag-64000; @b = gravity*100; $sRatio = @a/@b; MULT = @a *@b;" Rules: ; terminates a sub-expression @ prefix to a temporary name, which is a double precision floating point number to be used later in the same expression. $ prefix to a local GX variable name. Such names will be evaluated to the variable value at the time Create_EXP is called. All other tokens are assumed to be channel names.
