Reading and Writing Values

 

    You can store Glish values to a file and read them from a file using write_value() and read_value():

write_value(value, file)
    writes a representation of the given value to the file file, which is interpreted as a string.   Presently only values of type numeric, string, or record are supported, and those of type function and agent are not supported. Values of type reference are first dereferenced before being written.

write_value() returns T if successful and F if not.

read_value(file)
    reads a Glish value from the file file (interpreted as a string) and returns it, or F if it encountered problems.

Note that when stored in files Glish values correspond to SOS datasets (See Chapter 14, page , for a discussion of SOS).
