shortening my sequencing records without writing each record

[babyboomerboy]

I have a program that writes a series of numbers to a file that I can recall. The problem is I have to go into the program each time I want to write a different record. 
OPEN "RECORD16.DAT" FOR OUTPUT AS #1
FOR TTP = 1 TO 8
    FOR X = 1 TO 3
        PRINT #1, ALINE(X, TTP)
        PRINT #1, TIME(X, TTP)
    NEXT X
NEXT TTP
CLOSE #1

I want to be able to make a new record :record16.dat without going to the program and changing it, 
record 17.dat, or record18.dat or whatever. I also want to be able to recall this new record. 
I hope I was able to explain this for someone to understand how I can add to my data base without doing it manually. Thank you
