[net.micro.pc] DOS sub-directory reading.

langet@ecn-pc.UUCP (Timothy Lange) (11/12/85)

I finally found out how to read DOS directories as files.  First, I
tried opening the directory with an extended File Control Block and set
the attribute byte to directory.  This worked, the file got opened but
when I tried to read anything, I got the error for no data to be read.

Well, DOS is tricky, according to ihnp4!stolaf!krausej (Krause, James J.)
who pointed me to an article in PC Tech Journal, DOS sets the file size
of directories to 0!  So, after opening the directory I reset the file
size and hurray, I can read the directory entries.  I am writing a
program that will sort the file names in a directory alphabetically, if
anyone wants it, please just send me mail to the the assembler source.
I should have it done in about a week.

Now my next question, anybody have/know of a program that will be memory
resident and will save the current screen to disk so that the saved
screen image can be displayed at a later time?  I would like to save
screen graphs done by a package and display them one after the other
without using the graphics package, as for a presentation.
