Hi!

I have been using the program named 'PCTOOLS'.
That has many utilities. One of them is Disk view/Edit function.
This function shows data on diskette and let me update data
and write updated data on diskette.

'DITTO' package for Tape and Disk operation is installed in my site.
I read the output of DITTO and I found the file system in DASD partially.
By the way, how I can read and write data on DASD directly(?) ?
What is the basic method of FSOPEN,FSREAD,FSWRITE,etc macro?
In System Programmer's Guide, 'diagnose x'18' -- DASD I/O'.
I need a lot of examples and explanations.

                                   Thanks in advance.
                                      -Nso
