Identifiers

Because identifiers in Algol 68 can contain white-space, it is possible for you to key an identifier differently on two separate occasions in the Web 68 file. This is not a problem for tang, because it deletes all white-space from the identifier before storing it. However, this could lead to problems with weav. The policy has been adopted of outputting the identifier in the way it was first keyed. Thus the two identifiers

fl begin form and flbegin form
will appear in the index as fl begin form. However, the identifiers will be compared as flbeginform (all white-space deleted).
