Whenever an item reference is encountered during an RValue expansion that item is appropriately expanded. Standard-RValue expansion occurs at these points:

• a parameter passed to a function (not marked as do not expand)
• the value to be assigned in a map→
• the value to add to a vector→
• the value assigned in set→, default→, putin→

Refer to Function Call→ for additional expansion options used when calling functions with short syntax.

String Values

Usually this expansion implies producing a string. This results from using the provided value, replacing all items with their expanded value, and concatenating it all together.

set %One% First Item
Notice This is the %One%!
# Outputs:
# This is the First Item!

Object References

By default, in a form such as %Item% given in content, where there is no leading or trailing text/items to the expansion, the item will be expanding as the actual object form the context, it will not be converted to a string.

LValue's

No expansion is done on items used as LValues, but note that indirection→ will expanded to result in the item to be used.
