The detailed semantics of "the" ternary operator as well as its syntax differs significantly from language to language. A top level distinction from one language to another is whether the expressions permit side effects (as in most procedural languages) and whether the language provides short-circuit evaluation semantics, whereby only the selected expression is evaluated (most standard ...
All IF/THEN/ELSE conditional statements must be written on one line, although WHILE/WEND statements may group multiple lines. Functions can only be defined using the single line DEF FNf (x)= <mathematical function of x> statement (e.g., DEF FNLOG(base,number)=LOG(number)/LOG(base) ).
This line performs the actual task of writing the output. Console is a system object, representing a command-line interface (also known as a "console") and granting programmatic access to the operating system's standard streams. The program calls the Console method WriteLine, which causes the string passed to it to be displayed on the console.
GOTO line - Jump to program line; IF a THEN statement ELSE statement - Conditions (the statement can be just a line number) INPUT “message”;variable1,variable2 - Set variables to user-entered values (comma separated). A ? is printed after the message and before reading the values from the user.
Code statements have no terminating character other than a line ending (carriage return/line feed), and versions since 3 allow for multi-line statements for concatenation of strings or explicitly using the underscore character (_) at the end of a line [15] [16] A code comment is denoted by a single apostrophe (') character, like: ' This is a ...
Line vs. block – a line comment starts with a delimiter and continues to the end of the line (newline marker) whereas a block comment starts with one delimiter and ends with another and can cross lines; Nestable – whether a block comment can be inside another block comment

If-then-else flow diagram A nested if–then–else flow diagram. In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language constructs that perform different computations or actions or return different values depending on the value of a Boolean expression, called a condition.
