HELP DATAFILE David Hogg, Feb 1982 Revised Aaron Sloman Sep 2009 The procedure datafile allows certain Pop-11 data structures to be recorded on disk, and subsequently read back. To write a structure to disk, use: struct -> datafile(filename); Similarly, to read a structure back from disk, use: datafile(filename) -> struct; The permitted datatypes are: Words, numbers, lists, vector types, record types, arrays, ordinary properties, booleans, named procedures, closures of named procedures. Since arrays can be organised by row or by column, that information about an array is stored by the updater of datafile and restored when datafile recreates the array from a stored version. --- C.all/help/datafile --- Copyright University of Sussex 2009.
