Problem Statement

Take the string     alphaBETA     and demonstrate how to convert it to:

Use the default encoding of a string literal or plain ASCII if there is no string literal in your language. Note: In some languages alphabets toLower and toUpper is not reversable. Show any additional case conversion functions   (e.g. swapping case, capitalizing the first letter, etc.)   that may be included in the library of your language.

Let's start with the solution:

#lang transd

MainModule: {
    _start: (λ 
        (with s "alphaBETA"
            (lout (toupper s))
            (lout (tolower s)))
    )
}
