Saving a structure to a file and reading it back ?

How do I save a user defined structure (by using defStruct) to a file and how do I retrieve it back ? Can I just use outfile( ... ) and fprintf ? Thanks, Michele

    Not directly. It's easy enough to write something that would do this though - for example, the following writes out a SKILL statement to recreate the structure (note, it doesn't assign the result to a variable, so you'd need to adapt it to your needs).

    procedure(ABwriteStruct(file struct)
    fprintf(file "make_%s%L\n" type(struct)
    foreach(mapcan arg struct->?
    list(concat(? arg) get(struct arg))
    )
    )
    )

    Regards,

    Andrew.
