The servos seem to move automatically, regardless of the stimulus, and the button doesn’t seem to make anything happen yet. The problem may be with the “// //” notes, not sure. The second If-Else statement was to make the servos move if the bumper is pressed.Note that the light threshold will vary depending. Use the program below in the task main() section of the program between the curly braces.
ROBOTC IF ELSE CODE
A while loop is a structure within ROBOTC which allows a portion of code to be run over and over, as long as a certain condition remains true.

$ ERROR!!! Activity While Loops and If-Else Structures – VEX. We should instead use if-then-else statements as follows:Įlse if gpa>= 3.0 then gpagroup = "Good" Įlse if gpa >= 2.String text = “” If variable > 5 text = “one” else if variable else text = “three” In Robot Framework. If gpa >= 2.5 then gpagroup = "Satisfactory" If gpa>= 3.5 then gpagroup = "Excellent Grades" "Satisfactory" for those with a gpa greater than or equal to 2.5."Good" for those with a gpa greater than or equal to 3.0 and."Excellent Grades" for those with a gpa greater than or equal to 3.5,.Suppose we want to create a variable called gpagroup which takes on one of 3 values: SAS code follows the rules of logic: SAS evaluates if-then statements in the order in which they appear in the datastep. The value "Good standing" is not the same as the value "good standing". The exception is in the value of character variables.

Note that SAS does not generally distinguish between upper and lower case (you can use either). If gpa= 3.0 then group = "good standing"
![robotc if else robotc if else](https://docsbay.net/assets/images/while-loops-and-if-else-structures.jpg)
The new variable called group takes on one of two values: "good standing" if a person's gpa is greater than or equal to 3.0 and "not good standing" if a person's gpa is less than 3.0. The following code creates a new variable called group from an existing variable called gpa. SAS will keep evaluating the if-then-else-if statements until it encounters the first true statement.Ĭharacter variable data must always be enclosed in quotes. Note that this if-then-else-if statement could equivalently be writtenĪn if statement can be followed by exactly one else statement or by many else-if statements.

Note that the above statement could equivalently be writtenĪn optional else statement can be included (if-then-else) to provide an alternative action when the if expression is false.įor a person whose age is less than 65, the variable older will equal 0.Īn optional else-if statement can follow the if-then statement. For a person whose age is less than 65, the variable older will be missing. When the expression is false, SAS ignores the statement following then. When the expression is true, the statement following then is executed. Creating New Variables Using if-then if-then-else and if-then-else-then StatementsĪn if-then statement can be used to create a new variable for a selected subset of the observations.įor each observation in the data set, SAS evaluates the expression following the if.
