I have recently installed mbasic 1.02 on my Tandy 6000 -
one reason for me to do this was the availability of the
ON BREAK GOSUB
command -
This seems to work alright when executing arithmetic and logical commands.
However, when I attempt to use it when the program is waiting for keyboard
input, it produces an error and dies:
10 ON BREAK GOSUB 100
20 PRINT "hello"
30 INPUT J
40 PRINT "hello2"
50 GOTO 20
100 RETURN
when waiting for input produces:
Device I/O error
Fatal Error - BASIC Terminated
Of course the principal benefit of this command is to allow a true break as
well as to prevent an accidental striking of the key to interfere with
program execution for the un-inititated. (I mean, nobody really gets in
endless loops anymore do they?)
Does anyone have a fix for this or a way around?
thanks
