Yes and no.

Using the OPEN command, you can only open one file at a time. This really sucks
when you want to read from one file and write to another. The way you work
around this is to use the buffer. VADV's buffer is a file in your main VADV
directory called Bx.TMP (where x is a node number). So you can read and write
to two files like so:

' Set variable to the buffer.
LET B0 = "B" % !12 % ".TMP"

' Open file 1 to read from.
OPEN "FILE1.TXT", "I"

' Clear the buffer.
BUFFER CLEAR

Loop:
' Read a line.
READ L0

' If the end of the file, exit the loop.
IF L0 = "!EOF!" GOTO Loop_Exit

' Write it to the buffer.
BUFFER APPEND, L0
GOTO Loop

Loop_Exit:
' Close the open file.
CLOSE

' Now the entire file is in the buffer.. so you can copy it somewhere or
' whatever. Note: This example has no practical use.. any changes you want
' to make to the file need to be done during the loop.
LET Z0 = "COPY " % B0 % " " % "NEWFILE.TXT"
SHELL Z0


Hope that helps.
