Chapter 2 Program Instructions
Examples Allow sequential output to the printer's display using the OPEN statement
this way:
10 OPEN "console:" FOR OUTPUT AS #1
20 PRINT#1:PRINT#1
30 PRINT#1, "GONE TO LUNCH"
40
RUN
PRINT#1, "BACK SOON";
The text will appear on the printer's display as:
GONE TO LUNCH
BACK SOON
Open the file "PRICELIST" for random access with the reference number #8
and a record length of 254 bytes:
10 OPEN "PRICELIST" AS #8 LEN=254
Open the file "ADDRESSES" for sequential input with the reference number
#4 and a record length of 128 bytes.
10 OPEN "ADDRESSES" FOR INPUT AS #4
This example shows how a few lines can be added to a program to make
possible to unlock by an electronic key:
10 OPEN "lock:LCK1?PAS1" FOR INPUT AS #1
20 INPUT#1, A$
30 IF A$ AND 1 1 THEN GOTO 90000
.....
.....
.....
80000 CLOSE #1
90000 PRINT "Access to program denied!"
90010 END
