I want to rewind a file to the beginning.  Is there a command equivalent to the rewind command in C for VB.  If not, without closing the file and opening it again, how would one do this?

LJ,

What you could do is to open the file with the mode "Binary" (Open FileName.txt for Binary ), and then use the command Get to restart from the beginning of the file.

BTW, I don't see what's wrong with closing a file and reopening it right away ...

Steve.

Because I have to bounce each record in the file off of this other file and there are 2,000 records.  It seems to take longer when i close and reopen for each record.

If the records are fixed length and you know the record number you can use the SEEK command to reposition the pointer in the file without having to close & reopen. Will be *MUCH* faster esp if disk file can be cached.

BTW: SEEK to 0 will rewind the file if you need to do a sequential search.
