Summary of Programming Constructs

Please see the table below for a list of Analytica programming constructs, their meanings, and links to references with more details, if available.

Construct	Meaning:	For more, see
`e1; e2; … ei`	Semicolons join a group of expressions to be evaluated in sequence
`BEGIN e1; e2; …` `ei END`	A group of expressions to be evaluated in sequence
`(e1; e2; … ei)`	Another way to group expressions
`m .. n`	Generates a list of successive integers from `m` to `n`
`Var x := e`	Define local variable `x` and assign initial value `e`
`Index i := e`	Define local index `i` and assign initial value `e`
`x := e`	Assigns value from evaluating `e` to local variable `x`. Returns value `e`.
`While Test` `Do Body`	While `Test` is True, evaluate `Body` and repeat. Returns last value of `Body`.
{ comments } /* comments */	Curly brackets { } and /* */ are alternative ways to enclose comments to be ignored by the parser.
'text' "text"	You can use single or double quotes to enclose a literal text value, but they must match.
`For x := a DO e`	Assigns to loop variable `x`, successive atoms from array `a` and repeats evaluation expression `e` for each value of `x`. Returns an array of values of `e` with the same indexes as `a`.
`For x[i, j…] := a DO e`	Same, but it assigns to x successive sub-arrays of `a`, each indexed by the indices, `[i, j …`
`\ e`	Creates a reference to the value of expression `e`.
`1`	`VAR result := [1];`
`\ [i, j …] e`	Creates an array indexed by any indexes of `e` other than `i, j …` of references to sub-arrays of e each indexed by `i, j ….`
`# r`	Returns the value referred to by reference `r`.
