# FCL - Forth Calculator's Language FCL is the programming language of an Android app called Forth Calculator. It is a Forth dialect with optional local variables, complex data structures, quotations and Java interoperability. ```forth : fib ( n1 n2 -- n1 n2 n3 ) 2dup + ; : nfib ( n -- .. ) -> n ( local variable ) 0 1 n { fib } times ; ( quotation ) ``` Besides all the high-level features, FCL supports the traditional Forth programming structures and uses the same compilation model (compile/interpret mode, dictionary, immediate words, etc.) as traditional Forth systems. ## The Syntax ## Locals ## Maps ## List ## HTTP
