Random Access Files

[Colin Meeks]

Is it possible to have random access files as opposed to serial access.
Basically what I would like to be able to do is be able to write data within
a file, without having to

    1.    Read the first part
    2.    Write the first part
    3.    Write the bit I want
    4.    Read the final part
    5.    Write the final part

I would like to be able to do something like

    1.    Seek the potion to write
    2.    Write
    3.    Close file

I don't mean writing code that hides the methods of the first example.  If I
remember correctly you can do random access files in GWBasic.

Anyone have any pointer??

Thanks

Colin
