Syntax
% format-modifier @(argument-name)
A format item recognized only within macro declarations. Allows tokens passed as macro arguments to be inserted into strings.
If the argument used in a "%@" format is a string, the quotation marks delimiting the string are removed as a result. If the argument consists of several tokens, they are separated by single spaces.
The "u" and "l" format modifiers are permitted with the "%@" format item. The effect is to uppercase ("u") or lowercase ("l") the argument at the point it is copied into a string in the macro body.
