This question is about Klas Engwall's LFN library.

I need to save database as SDF (ASCII) file with a long file name.  Is
there a LF version of COPY_TO command or is doing a two-step procedure
(below) the only option?

   COPY TO temp.txt SDF
   LF_FRename("temp.txt", "langname.longextension")

TIA, Eugene

He does not describe having done this, and if you object to having
these two lines in your root code, you could always wrap in in your
own LF_CopyTo()...

Or update to xHarbour...

The supply of functions is a reflection of the demand <g>

Yes, that's the way to do it. Just remember to delete
langname.longextension if it already exists or LF_Frename will fail.

Klas,

Thank you very much for your reply.

Missed that one. Will add.

Another question (since I have not tested myself yet).  Will files
like 'longfilename.extension1.extension2.extension3' be acceptable to
your LF_ functions?

TIA, Eugene

My LF_* functions do not care what characters you pass in file name
arguments, but the NTVDM may object to some. I have had reports about
the Euro sign not working, for example. But there is nothing special
with dots, they are just like any other character. The difference
between the part of the file name before a dot and the part after the
dot just lives in the mind of those of us who started working with
computers when the length of a file name was limited to 8 plus 3
characters.

Klas

Klas,

Thank you very much for the clarification. I got my process working.

Klas,

I have two more LF_ questions (if I may)

1. Will functions that allow wild-cards accept something like
"l*.txt.*"?

2. Does LF_FERASE accept wild-cards or do I have to use LF_DIRECTORY
and call LF_FERASE via AEVAL do delete the files individually?

TIA, Eugene

Did you try it? Please don't rely on me to provide all the answers. I
may not be around forever. :-)

LF_Directory() is one way to do it. Another way is to run
LF_FindFirst() and LF_Ferase() in a loop until LF_FindFirst() returns
an empty string. Remembeer to kill the FindFirst handle before looping
back. Or use LF_FindFirst() and LF_FindNext(), but that requires
slightly more coding.

Klas
