Hello Steven,
I have done this sort of ting with logging files on a PC. What I have
done in the past is build a base file name (usually I use a variation on
today's dat3). I will then start a loop that appends a number from the
loop counter to the base name. Then I try to read something from that
filename, using a FROM FILE box with an ERROR output. If the object pings
the ERROR output, then that file does not exist, and I break from the loop
and return that filename. If the Read returns some value, then I close the
file, and go to the next iteration of the loop. If I run out of possible
numbers, I will return an error indicator to the user.
I have built this into a function that takes a DIRECTORY and a FILE
IDENTIFIER as inputs and returns the new file name. You could use the same
method to determine a plot file name before you begin your plot to make a
new file .

In the UNIX version of Vee 4.01, you can plot to a directory, /tmp/veeplot
When you do this repeatedly you get files with names:
plot1
plot2
plot3 ...
In the PC version of Vee 4.01 you can set up a printer in NT, with the driver
of your choice, which prints to a file.
The problem is, you have to supply the file name. Is there a way to to get
the same result as in the UNIX case?
