Conditions are used in any case where a branch, or a boolean value is required (as explicitly marked in a function). more⇛

default sets an item to a default value if the item is not yet defined. more⇛

exec is similar to call→ except the called unit is executed in a new Logical Root→. This effectively isolates this unit from the calling test. more⇛

A function can be called in three different manners

• with call→
• as a standalone short name
• as part of a Extended-RValue expansion→

User defined functions may be defined in the Script.FunctionMap context item. more⇛

If the condition→ is met, then execute the "then" block, otherwise execute the "else" block. The "else" block is optional, in which case nothing will be executed if the condition is not met. more⇛

Simple Items

Adds an expanded RValue to the vector item referenced. more⇛
