Find & read oddly named files?

[Robert E. Carneal]

Can Powerbasic for DOS make use of double periods in filenames?

I.e., Can I open for output, open for input, etc., names like
this:

ANDERSON.IND.DAT
ANDERSON.CEM.DAT
ANDERSON.MED.DAT
ANDERSON.COD.DAT <IMG SRC="http://www.powerbasic.com/support/forums/confused.gif" ALT="confused">

Problem: Keeping applications from seeing an extension that
application recognizes, and attempting to open it.

Goal: Having other applications leave the data for my cemetery
program alone so the data does not get corrupted.

Would just changing the attributes before opening it solve the
problem, I wonder? How have some of you solved this?

Thank you.

PB/DOS (and DOS) do not natively support LFNs. There are, however, interrupt functions available to DOS to handle LFNs when your program is running in a DOS box under Windows.

Understood. Can/do you recommend a source to read about
interrupt functions and LFNs please?

Thank you.

There are LFN libraries in the Downloads section. They don't work in
all cases, though-- check 'em on your expected target machines. (The
routines are sound enough, it's just the check for "is LFN available?"
that's shaky). Contact the authors...
