       code-blocks - Golf documentation (program-flow)

DESCRIPTION

       CODE BLOCKS

       Use  curly  braces  ("{"  and  "}")  to  open  and  close  a code block. They create a separate scope for
       previously non-existing variables defined within them, which begins with "{" and ends with "}". Note that
       if a variable existed in an outer scope, it cannot be created in the inner scope.

       Note that if-true, run-query, start-loop and read-line statements contain implicit code  blocks,  meaning
       the code between them and the accompanying end-statement is within implicit "{" and "}".

EXAMPLES

       The  following  code  will  first print out "outside" and then "inside" twice, illustrating the fact that
       variable "s1" is defined only in the outer scope once. Variable "s2" exists only in inner scope:

           begin-handler /scope public
               @<<print-out s1>>
               set-string s1="outside"
               {
                   set-string s2="inner variable"
                   set-string s1="inside"
                   @<<print-out s1>>
               }
               @<<print-out s1>>
           end-handler
