Event handler structure

Code:
{on event-type do body}

{on event-type at target-var[:target-type] do body}

{on event-var:event-type at target-var[:target-type] do body}

where

event-var:event-type: binds a variable to the event.
target-var[:target-type]: binds a variable to the target.
body is the code for the event handler procedure.

Branching expressions

Code:
{if condition-1 then 

    code-block-1 

 elseif condition-2 then 

    code-block-2 

 elseif condition-3 then 

    code-block-3 

    ... 

 elseif condition-n then 

    code-block-n 

 [else 

     code-block-n+1] 

}

where

condition-1, condition-2, ...: are Boolean expressions.
code-block-1, code-block-2, ...: each consist of one or more Curl language expressions.

switch

The switch expression has the following syntax:

Code:
{switch compare-expr [using compare-operator] 

     case value-1 do 

        code-block-1 

     case value-2 do 

        code-block-2 

        ... 

     case value-n do 

        code-block-n 

        [else code-block-n+1] 

    }

where

compare-expr, value-1, value-2, value-n: are Curl language expressions. These expressions can evaluate to any Curl language type.
compare-operator: the operator that the Curl language uses when comparing compare-expr to value-1, value-2, and so on.
code-block-1, code-block-2, code-block-n: consist of one or more Curl language expressions.
