OSI Definition ToolAPI Syntax Definition : Conditional Expressions : Syntax

Syntax

The syntax require that a conditional expression will begin with the operator “?<begin>” end with the operator “?<end>” and will contain in between the operators: “?<?>” and then “?<:>”.

So, a conditional expression looks like:

?<begin> sub expression 1 ?<?> sub
expression 2 ?<:> sub expression 3 ?<end>
 

All that is legal in an API definition might appear before the ?<begin> and after the ?<end> markers.
