Example
LINE INPUT, "NAME? "; N$
inputs data from the keyboard and stores it in variable N$.
3. To write data to the file, use the WRITE# statement (you can also
use PRINT#, but make sure you delimit the data).
Example
WR ITE# 1, N$
writes variable N$ to the file, using buffer 1 (the buffer used to
OPEN the file). Remember that data must go through a buffer
before it can be written to a file.
4. To ensure that all the data was written to the file, use the CLOSE
statement.
Example
CLOSE 1
closes access to the file, using buffer 1 (the same buffer used to
OPEN the file).
Sample Program
10 OPEN "0", 1, "LIST/EMP"
20
LI NE INPUT "NAME? "; N$
30 IF N$
=
"DONE" THEN 60
1I0 WRITE# 1, N$
50 PR I NT: GOTO 20

RUN
NOTE: The file "L1ST/EMP" stores the data you input through the
aid of the program, not the program itself (the program
manipulates data). To save the program above, you must assign it
a name using the SAVE command (refer to Chapter 1).
Example
SAI.IE "PAYROLL"
would save the program under the name "PAYROLL".
NOTE: Every time you modify a program, you must SAVE it again
(you can use the same name); otherwise, the original program
remains on disk, without your latest corrections.
5. To access data in the file, reOPEN it in the "I" (input) mode.
Example
OPEN "I", 1, "LIST/EMP"
