TOKEN END IF

ALIAS None

The End If token is used to mark the end of an If conditional block. Every If statement must have a corresponding End If to define where the conditional structure terminates. The End If statement closes the entire If-Elif-Else chain and is required regardless of whether Elif or Else clauses are present.

Syntax

The short syntax structure uses the words END IF:

IF CONDITION
    STATEMENTS
END IF

The long syntax structure uses the words END IF:

IF CONDITION
    STATEMENTS
END IF

Basic End If Usage

End If is required to close every If statement.

Example: Simple If with End If

NEW INT age = 20
IF age >= 18
    PRINTLN "You are an adult"
END IF
PRINTLN "Program continues"
// Displays "You are an adult" and "Program continues"

Example: If-Else with End If

NEW INT score = 85
IF score >= 90
    PRINTLN "Grade: A"
ELSE
    PRINTLN "Grade: B or below"
END IF
PRINTLN "Grading complete"
// Displays "Grade: B or below" and "Grading complete"

Example: If-Elif-Else with End If

NEW FLOAT temperature = 75.0
IF temperature >= 90.0
    PRINTLN "Hot"
ELIF temperature >= 70.0
    PRINTLN "Warm"
ELSE
    PRINTLN "Cool"
END IF
PRINTLN "Temperature check complete"
// Displays "Warm" and "Temperature check complete"

Example: Multiple Statements After End If

NEW INT x = 5
IF x > 10
    PRINTLN "x is large"
END IF
PRINTLN "After conditional"
PRINTLN "Program running"
NEW INT y = 20
// All statements after END IF execute normally

End If Closes Entire If Block

End If terminates the entire conditional structure, including all If, Elif, and Else clauses.

Example: End If After Multiple Elif

NEW INT day = 3
IF day == 1
    PRINTLN "Monday"
ELIF day == 2
    PRINTLN "Tuesday"
ELIF day == 3
    PRINTLN "Wednesday"
ELIF day == 4
    PRINTLN "Thursday"
END IF
PRINTLN "Day processed"
// Displays "Wednesday" and "Day processed"

Example: End If After Long Chain

NEW INT score = 72
IF score >= 90
    PRINTLN "Grade: A"
ELIF score >= 80
    PRINTLN "Grade: B"
ELIF score >= 70
    PRINTLN "Grade: C"
ELIF score >= 60
    PRINTLN "Grade: D"
ELSE
    PRINTLN "Grade: F"
END IF
PRINTLN "Report card generated"
// Displays "Grade: C" and "Report card generated"

Example: Multiple Conditionals in Sequence

NEW INT x = 15
NEW INT y = 20
IF x > 10
    PRINTLN "x is greater than 10"
END IF
IF y > 10
    PRINTLN "y is greater than 10"
END IF
// Both conditionals are independent
// Displays both messages

End If with Nested Conditionals

Each If statement requires its own End If, including nested conditionals.

Example: Nested If with Multiple End If

NEW INT age = 25
NEW BOOL hasLicense = TRUE
IF age >= 18
    IF hasLicense == TRUE
        PRINTLN "Can drive"
    ELSE
        PRINTLN "Need license"
    END IF
ELSE
    PRINTLN "Too young"
END IF
PRINTLN "Check complete"
// Inner IF needs END IF, outer IF needs END IF

Example: Multiple Levels of Nesting

NEW INT level = 2
NEW INT points = 150
IF level >= 1
    IF level >= 2
        IF points >= 100
            PRINTLN "Advanced player"
        END IF
    END IF
END IF
PRINTLN "Player status checked"
// Three IF statements require three END IF statements

Example: Nested If-Elif-Else

NEW STR userType = "premium"
NEW INT accountAge = 15
IF userType == "premium"
    IF accountAge >= 12
        PRINTLN "Long-term premium member"
    ELIF accountAge >= 6
        PRINTLN "Established premium member"
    ELSE
        PRINTLN "New premium member"
    END IF
ELIF userType == "standard"
    PRINTLN "Standard member"
END IF
PRINTLN "Member status complete"
// Inner IF-ELIF-ELSE needs END IF
// Outer IF-ELIF needs END IF

Example: Complex Nesting

NEW INT a = 10
NEW INT b = 20
IF a > 5
    PRINTLN "a is greater than 5"
    IF b > 15
        PRINTLN "b is greater than 15"
        IF ( a + b ) > 25
            PRINTLN "Sum is greater than 25"
        END IF
    END IF
END IF
PRINTLN "All checks complete"
// Each IF requires its own END IF

End If Marks Execution Boundary

Code after End If always executes, regardless of which branch was taken in the conditional.

Example: Guaranteed Execution After End If

NEW INT value = 5
IF value > 10
    PRINTLN "Inside IF block"
ELSE
    PRINTLN "Inside ELSE block"
END IF
PRINTLN "This always executes"
// "This always executes" runs regardless of condition

Example: Variable Access After End If

NEW STR status = ""
IF TRUE
    SET status = "active"
END IF
PRINTLN "Status: " .. status
// Variables modified inside IF are accessible after END IF

Example: Sequential Logic After End If

NEW INT score = 85
NEW INT bonus = 0
IF score >= 80
    SET bonus = 10
END IF
NEW INT finalScore = score + bonus
PRINTLN "Final score: " .. finalScore
// Calculations after END IF use updated values

Example: Multiple Operations After End If

NEW INT x = 15
IF x > 10
    PRINTLN "Condition met"
END IF
SET x = x + 5
PRINTLN "x is now: " .. x
IF x > 20
    PRINTLN "x exceeds 20"
END IF
// Multiple statements and conditionals after END IF

End If in Loops

If statements inside loops require End If before the loop can continue to the next iteration.

Example: If Inside While Loop

NEW INT i = 1
WHILE i <= 5
    IF ( i % 2 ) == 0
        PRINTLN i .. " is even"
    ELSE
        PRINTLN i .. " is odd"
    END IF
    SET i = i + 1
END WHILE
// END IF closes the conditional before loop continues

Example: Multiple Conditionals in Loop

NEW INT num = 1
WHILE num <= 10
    IF num < 5
        PRINTLN num .. " is low"
    END IF
    IF num >= 5
        PRINTLN num .. " is high"
    END IF
    SET num = num + 1
END WHILE
// Each IF needs its own END IF within the loop

Example: Nested If in Loop

NEW INT i = 1
WHILE i <= 5
    IF i > 2
        IF i < 5
            PRINTLN i .. " is in range"
        END IF
    END IF
    SET i = i + 1
END WHILE
// Nested conditionals each need END IF

Example: Break After End If

NEW INT counter = 1
WHILE counter <= 10
    IF counter == 5
        PRINTLN "Stopping at 5"
        BREAK
    END IF
    PRINTLN "Count: " .. counter
    SET counter = counter + 1
END WHILE
// END IF comes before BREAK

End If Scope and Variables

Variables created or modified before End If remain accessible after End If.

Example: Variable Persists After End If

NEW STR result = ""
IF TRUE
    SET result = "completed"
END IF
PRINTLN result
// Displays "completed" - variable accessible after END IF

Example: Multiple Variable Updates

NEW INT total = 0
NEW INT count = 0
IF TRUE
    SET total = 100
    SET count = 5
END IF
NEW INT average = total / count
PRINTLN "Average: " .. average
// Variables updated in IF are used after END IF

Example: Conditional Variable Creation

NEW BOOL hasBonus = TRUE
NEW INT salary = 50000
NEW INT bonus = 0
IF hasBonus == TRUE
    SET bonus = 5000
END IF
NEW INT totalPay = salary + bonus
PRINTLN "Total compensation: " .. totalPay
// Displays "Total compensation: 55000"

Practical Applications

Example: Input Validation Complete

NEW INT age = 25
NEW BOOL validAge = FALSE
IF ( age >= 0 ) && ( age <= 120 )
    SET validAge = TRUE
    PRINTLN "Age is valid"
ELSE
    PRINTLN "Invalid age"
END IF
IF validAge == TRUE
    PRINTLN "Processing user data"
END IF
// Second conditional uses result from first

Example: Multi-Stage Processing

NEW INT score = 85
NEW STR grade = ""
IF score >= 90
    SET grade = "A"
ELIF score >= 80
    SET grade = "B"
ELIF score >= 70
    SET grade = "C"
ELSE
    SET grade = "F"
END IF
PRINTLN "Grade assigned: " .. grade
NEW BOOL passed = FALSE
IF grade != "F"
    SET passed = TRUE
END IF
IF passed == TRUE
    PRINTLN "Student passed the course"
END IF
// Multiple conditionals process sequentially

Example: Sequential Checks

NEW STR username = "admin"
NEW STR password = "pass123"
NEW BOOL authenticated = FALSE
IF username == "admin"
    PRINTLN "Username verified"
END IF
IF password == "pass123"
    PRINTLN "Password verified"
END IF
IF ( username == "admin" ) && ( password == "pass123" )
    SET authenticated = TRUE
END IF
IF authenticated == TRUE
    PRINTLN "Access granted"
END IF
// Each check completes before next begins

Example: Status Update Chain

NEW FLOAT balance = 1500.0
NEW STR accountStatus = "active"
IF balance >= 1000.0
    SET accountStatus = "premium"
    PRINTLN "Upgraded to premium"
END IF
PRINTLN "Current status: " .. accountStatus
NEW FLOAT fee = 0.0
IF accountStatus == "premium"
    SET fee = 0.0
ELSE
    SET fee = 10.0
END IF
PRINTLN "Monthly fee: $" .. fee
// Status from first IF affects second IF

Example: Error Handling Flow

NEW INT errorCode = 404
NEW STR errorMessage = ""
IF errorCode == 404
    SET errorMessage = "Not Found"
ELIF errorCode == 500
    SET errorMessage = "Server Error"
ELIF errorCode == 403
    SET errorMessage = "Forbidden"
ELSE
    SET errorMessage = "Unknown Error"
END IF
PRINTLN "Error " .. errorCode .. ": " .. errorMessage
NEW BOOL shouldRetry = FALSE
IF errorCode == 500
    SET shouldRetry = TRUE
END IF
IF shouldRetry == TRUE
    PRINTLN "Retrying request..."
END IF
// Error handling completes at END IF

Example: Configuration Builder

NEW INT userLevel = 2
NEW INT maxConnections = 10
IF userLevel >= 3
    SET maxConnections = 100
ELIF userLevel >= 2
    SET maxConnections = 50
ELIF userLevel >= 1
    SET maxConnections = 25
END IF
PRINTLN "Max connections: " .. maxConnections
NEW INT timeout = 30
IF userLevel >= 2
    SET timeout = 60
END IF
PRINTLN "Timeout: " .. timeout .. " seconds"
// Configuration built step by step

Example: Point Calculation System

NEW INT basePoints = 100
NEW INT multiplier = 1
NEW INT difficulty = 3
IF difficulty >= 3
    SET multiplier = 3
ELIF difficulty >= 2
    SET multiplier = 2
END IF
NEW INT totalPoints = basePoints * multiplier
PRINTLN "Points earned: " .. totalPoints
NEW INT bonus = 0
IF totalPoints >= 200
    SET bonus = 50
END IF
NEW INT finalPoints = totalPoints + bonus
PRINTLN "Final points: " .. finalPoints
// Points calculated across multiple conditionals

End If Position Requirements

Example: End If Must Close All Clauses

NEW INT x = 5
IF x > 10
    PRINTLN "High"
ELIF x > 5
    PRINTLN "Medium"
ELSE
    PRINTLN "Low"
END IF
// END IF must come after all IF/ELIF/ELSE clauses
PRINTLN "Conditional complete"

Example: End If Cannot Appear Early

NEW INT score = 85
IF score >= 90
    PRINTLN "A"
ELIF score >= 80
    PRINTLN "B"
END IF
// END IF closes entire IF-ELIF structure
// Cannot have more ELIF after END IF

Example: Proper If-Elif-Else-End If Order

NEW INT value = 50
IF value > 75
    PRINTLN "High"
ELIF value > 50
    PRINTLN "Medium"
ELIF value > 25
    PRINTLN "Low"
ELSE
    PRINTLN "Very Low"
END IF
// Order: IF -> ELIF( s ) -> ELSE -> END IF

End If with All Data Types

Example: Boolean Conditional

NEW BOOL isActive = TRUE
IF isActive == TRUE
    PRINTLN "System active"
END IF
PRINTLN "Status check complete"

Example: Integer Conditional

NEW INT count = 10
IF count > 5
    PRINTLN "Count exceeds threshold"
END IF
PRINTLN "Count processed"

Example: Float Conditional

NEW FLOAT temperature = 98.6
IF temperature > 98.0
    PRINTLN "Elevated temperature"
END IF
PRINTLN "Temperature reading complete"

Example: String Conditional

NEW STR command = "start"
IF command == "start"
    PRINTLN "Starting system"
END IF
PRINTLN "Command processed"

Important Notes

Every If statement must have exactly one End If.
End If must appear after all If, Elif, and Else clauses.
End If marks the end of the entire conditional structure.
Code after End If always executes regardless of which branch was taken.
Nested If statements each require their own End If.
End If has no condition or parameters.
Variables modified before End If remain accessible after End If.
Multiple If statements in sequence each need their own End If.
End If cannot appear before Elif or Else clauses.
Missing End If results in a syntax error.
