OCR Selection Commands

Concept	Keyword(s)/Symbols	Example
IF-THEN-ELSE	`if ... then`, `elseif ... then`, `else`, `endif`	`if answer == "Yes" then` `print("Correct")` `elseif answer == "No" then` `print("Wrong")` `else` `print("Error")` `endif`
CASE SELECT / SWITCH	`switch ... :`, `case ... :`, `default:`, `endswitch`	`switch day :` `case "Sat":` `print("Saturday")` `case "Sun":` `print("Sunday")` `default:` `print("Weekday")` `endswitch`

Useful Support	Syntax	Why it helps
Input / Output	`input(...)`, `print(...)`	Read a value first, then print the chosen outcome.
Assignment	`=`	Store the value you want to test, for example `score = 42`.
Comparison	`==`, `!=`, `<`, `<=`, `>`, `>=`	These decide which branch runs in an `if` statement.

Selection Tips	Remember	Check
Order matters	Put the most specific or highest condition first.	`if score >= 70 then` should come before `elseif score >= 50 then`.
One branch only	An `if / elseif / else` chain runs just one matching branch.	Once one condition is true, the later ones are skipped.
Use SWITCH for one value	`switch` is useful when you compare the same variable with several exact cases.	Add a `default:` branch for anything unexpected.
