This program prints "Hello world" Anything that comes after a ! character on a single line is ignored by the interpreter. Each line of input will have its own line of output, so place your line breaks carefully.Ĭomments can also be placed in programs.

If the string contains underscores, they will be printed as spaces.Ī valid Letterbox program is a series of function calls separated by spaces and/or line breaks. In lieu of this, Letterbox treats underscores (_) in strings as spaces. NOTE: No spaces are allowed in strings, because whitespace is not allowed within function calls. A string manipulator function has the form A:string where A is the function name, and everything after the colon (:) is the string you wish to pass in. Otherwise, does nothing.įor ease of I/O, Letterbox has some (albeit limited) string shortcuts. If a is true (nonzero), executes function F. Repeatedly executes function F, repeating a times.

Diese Website dient als neue zentrale Informationsplattform der deutschen Letterboxing-Gemeinde. where A is the function name, b is a variable argument, and F. Prefix functions are functions that take in other functions as arguments. Pauses execution, gets input from the user of a certain type, and stores the value in a Operations: equal to, and, or, xor (exclusive or)
This result will always be 0 (false) or 1 (true). Performs a boolean operation on b and c and stores the result in a. Operations: add, subtract, multiply, divide, equal to, greater than, less than Performs a mathematical operation on b and c and stores the result in a. are the variable arguments of the function. These take the form AXb., where A is the function name, X is a key letter that specifies what operation the function will perform, and b. Since there are only 26 possible simple function names in Letterbox, some functions have been combined into one in order to save letters for other functions that might possibly be implemented in the future. Using uppercase A as an argument resets all variables.īoolean negation. Variables are considered "true" if their value is nonzero, and "false" if their value is zero.įollowing are the four types of Letterbox function formats:Ī simple function follows the format Ab., where A is the function name and b. All Letterbox function names are singular uppercase English letters. No whitespace is allowed between these characters, as spaces are what separate Letterbox statements. A is the name of the function we are calling while b and c are two variables we are passing in as arguments. They can also technically hold strings (as the language is built over Python) but this implementation is buggy at best.Ī Letterbox function call generally looks like Abc. Each variable can hold a single number, which can be an integer or a decimal, positive or negative. Letterbox is case-sensitive, and uppercase letters are not variable names. Each is labeled as a lowercase letter from a to z and each is set to 0 by default. registers, for those familiar with Assembly). Session 4 – Let’s Talk About Letterbox and Contact – Thinking about siblings.Letterbox programs manipulate a bank of 26 variables (a.k.a. Session 3 – Let’s Talk About Letterbox and Contact – Who and how? Session 2 – Let’s Talk About Letterbox and Contact – What is it and why does it matter? 23rd March 2022, 10 – 12noon The session will be held online via Zoom. Adopters should also leave with a greater understanding of the purpose of post-adoption contact (relationships and identity building) and the key messages from the research evidence around post-adoption contact.
It will be an opportunity to hear how it can pay to think creatively about who your child might benefit from having contact with – apart from just the obvious immediate birth family – as well as the different types of contact arrangements that might be possible (direct, indirect, online). The session will be relatively informal with the chance to participate in the discussion, share and ask questions of those present. They will also be joined by at least one experienced adopter who will share their stories and experiences of contact.
This session will be facilitated by Eve Payne the Sharing Stories Life Story Worker and Lindy Wootton the CCS Sharing Stories Manager.

Feel free to come to all or just those you fancy. The third in a series of four informal sessions where we open up the thorny subject of Contact with birth families for adopted children and young people.
