Column delimiters

The default column delimiter is a space character, although the READF command does have the ability to use other delimiters by setting the DELIM parameter. It is possible for more than one delimiter character to be used, e.g. using &\ would be a good way to read a table that was in TEX format (& for a L^ATEX tabular format table). A null string for the DELIM parameter has the same effect as a single space.
