If you list or View the file DATECONV.BI, you will note that the library
functions expect integers "hibyte%" and "lowbyte%."

To put this into program context:  Say you have defined the location of
the DOS date in memory as dateoff%.  If you then issue the following
code, you will have the proper parameters sent to the function:

datelow% = PEEK(dateoff%)
datehi% = PEEK(dateoff%+1)
fdate$ = dosdate$(datelow%, datehi%)

fdate$ will contain a string in the form mm/dd/yyyy.

The analogous procedure applies for obtaining a hh:mm:ss time string.

The functions work by applying appropriate masks to the converted DOS
date and time.  By "converted," I mean "hibyte% * 256 + lowbyte%".  The
masks aren't too hard to figure out once you know how DOS stores dates and
times (I got the information from The Waite Group's MS-DOS Bible by Steven
Simrin).

I will be happy to send source code as an educational tool; simply send a
check for $5.00 U.S. dollars (to cover expenses) to:

     Brian D. Rogers

Hope you find these functions as useful as I do.  I will soon be uploading
a file into either the IBMPRO forum or the MSBASIC forum (another directory
utility) that uses early variants of these functions.  Look for it!
