Time Stamp change?

Probably - though it would be easier in QuickBasic.
That is because you need to use a call interrupt which is
available in QuickBasic.
In Qbasic you would have to use a call absolute routine
to call the interrupt.
I dont recall off hand which one it is though it's probably
part of Interrupt 20H.
I have a listing of the interrupt calls on my site in the files section

QuickBasic includes a compiler Qbasic does not.
QuickBasic has a little more available.
Qbasic replaced GWBASIC starting with DOS version 5.0
QuickBasic 4.5 is still the most popular version and most
libraries you see are written for that version.
PDS (QuickBasic version 7.x) included a currency floating
point type (four decimal places) for better handling of
dollars and cents calculations and a isam file system.
(indexed sequential access mode) for easier creation /
maintenance of databases.

Ok, I found some stuff in an interrupt file, now what do I do with it?
-04h DWORD pointer to FAR routine to update directory info in related SFT
entries
call with ES
I -> system file table entry for file (see below)
AX = subfunction (apply to each related SFT)
00h: update time stamp (offset 0Dh) and date
stamp (offset 0Fh)
