Examples

This example illustrates how activating the F1 key (id. No. 10) will make the

program branch to a subroutine, which contains the PRINTFEED statement.

Note line 30 where the execution will wait for the key to be pressed.

10 ON KEY (10) GOSUB 1000

20 KEY (10) ON

30 GOTO 30

.....

1000 FONT "Swiss 721 BT"

1010 PRPOS 30,100

1020 PRTXT "HELLO"

1030 PRINTFEED

1040 END

RUN

The same example can be written without line numbers this way:

IMMEDIATE OFF

ON KEY (10) GOSUB QQQ

KEY (10) ON

WWW: GOTO WWW

.....

QQQ: FONT "Swiss 721 BT"

PRPOS 30,100

PRTXT "HELLO"

PRINTFEED

END

IMMEDIATE ON

RUN
