UCase

Syntax:

  output = UCase(source)

Command Availability:

Available on all microcontrollers.

Explanation:

The UCase function converts all of the letters in the string source to upper case, and returns the result. Characters that are not letters are left unchanged.

Example:

    'Set chip model
    #chip 16F1936

    'Set up hardware serial connection
    #define USART_BAUD_RATE 9600
    #define USART_TX_BLOCKING


    'Fill a string with a message
    Dim TestData As String
    TestData = "Hello, world!"

    'Display the string in upper case
    'Will display "HELLO, WORLD!"
    HSerPrint UCase(TestData)          ' <<< the UCase instruction
    HSerPrintCRLF

Key line: UCase(TestData) — returns TestData with every letter converted to upper case, leaving the comma and exclamation mark untouched.
