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 PRINT#1, "BACK SOON";

RUN

The text will appear on the printer’s display as:

GONE TO LUNCH

BACK SOON

Open the ﬁ le "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 ﬁ le "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 it

possible to unlock it using 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
