AssignmentsIdentifiers allow objects to be assigned to names during the parse
stage. To assign an identifier, use name An identifier can be created with any string for its name, but you will only be able to refer to identifiers whose names begin with a letter, being entirely alphabetical. It is impossible to refer to an identifier whose name is the same as the name of a keyword. The right hand side of an identifier assignment is parsed completely before the assignment is done, so it is allowed to redefine an identifier in terms of its old value, e.g. foo = \foo * 2.0 When an identifier is referenced, the information it points to is copied. For this reason, an identifier reference must always be the first item in a block. \paper { foo = 1.0 \paperIdent % wrong and invalid } \paper { \paperIdent % correct foo = 1.0 } |
